Answers
Answer:
x = 10/9
Step-by-step explanation:
Solve for x:
(4 x)/5 + 4/3 = 2 x
Put each term in (4 x)/5 + 4/3 over the common denominator 15: (4 x)/5 + 4/3 = (12 x)/15 + 20/15:
(12 x)/15 + 20/15 = 2 x
(12 x)/15 + 20/15 = (12 x + 20)/15:
(12 x + 20)/15 = 2 x
Multiply both sides by 15:
(15 (12 x + 20))/15 = 15×2 x
(15 (12 x + 20))/15 = 15/15×(12 x + 20) = 12 x + 20:
12 x + 20 = 15×2 x
15×2 = 30:
12 x + 20 = 30 x
Subtract 30 x from both sides:
(12 x - 30 x) + 20 = 30 x - 30 x
12 x - 30 x = -18 x:
-18 x + 20 = 30 x - 30 x
30 x - 30 x = 0:
20 - 18 x = 0
Subtract 20 from both sides:
(20 - 20) - 18 x = -20
20 - 20 = 0:
-18 x = -20
Divide both sides of -18 x = -20 by -18:
(-18 x)/(-18) = (-20)/(-18)
(-18)/(-18) = 1:
x = (-20)/(-18)
The gcd of 20 and -18 is 2, so (-20)/(-18) = (-(2×10))/(2 (-9)) = 2/2×(-10)/(-9) = (-10)/(-9):
x = (-10)/(-9)
Multiply numerator and denominator of (-10)/(-9) by -1:
Answer: x = 10/9

Answers
The probability of getting exactly 3 heads when a penny is flipped 9 times is approximately 0.1641.
The expression that represents the probability of getting exactly 3 heads when a penny is flipped 9 times is:
p(3 successes) = (9 C 3) * (0.5)^3 * (0.5)^(9-3)
Where:
"p(3 successes)" represents the probability of getting 3 heads.
"9 C 3" represents the number of ways to choose 3 flips out of 9 flips (also known as the binomial coefficient). This is calculated as 9! / (3! * (9-3)!), which simplifies to 84.
"0.5" represents the probability of getting heads on a single flip of a fair penny.
"(0.5)^(9-3)" represents the probability of getting tails on the remaining 6 flips, since the probability of getting either heads or tails on a single flip is 0.5.
Simplifying the expression, we get:
p(3 successes) = (9 C 3) * (0.5)^9
p(3 successes) = (84) * (0.5)^9
p(3 successes) ≈ 0.1641
Therefore, the probability of getting exactly 3 heads when a penny is flipped 9 times is approximately 0.1641.

To rename a fraction as a whole number or mixed number, we divide the numerator by the denominator. If the result is a whole number, then the fraction is renamed as that whole number. If the result is a mixed number, we take the integer part as the whole number and the fractional part as the numerator of the proper fraction. For example, 7/8 can be renamed as a mixed number by dividing 7 by 8, which gives 0.875. The integer part is 0, so we take the fractional part 0.875 as the numerator of the proper fraction. We can simplify it to 7/8. Similarly, we can rename the other fractions in the same way.

prove that for each natural number n > 43, we can write n = 6xn 9yn 20zn 15. strong induction 117 for some nonnegative integers xn, yn, zn. then prove that 43 cannot be written in this form
Answers
For each natural number n > 43, we can express it as n = 6xn + 9yn + 20zn + 15, where xn, yn, and zn are nonnegative integers. Additionally, we have shown that 43 cannot be written in this form.
To prove that for each natural number n > 43, we can write n = 6xn + 9yn + 20zn + 15, where xn, yn, and zn are nonnegative integers, we will use strong induction. The base case will be n = 44, and we will assume that the statement holds for all natural numbers up to k, where k > 43. Then we will prove that it holds for k+1.
Base Case:
For n = 44, we can express it as:
44 = 6(1) + 9(1) + 20(1) + 15
Inductive Hypothesis:
Assume that for every natural number m, where 44 ≤ m ≤ k, we can express m as:
m = 6x + 9y + 20z + 15
for some nonnegative integers x, y, and z.
Inductive Step:
We need to prove that for k+1, we can express it in the given form.
For k+1, there are three cases to consider:
Case 1: k+1 is divisible by 6
In this case, we can express k+1 as:
(k+1) = 6x' + 9y' + 20z' + 15
where x' = x + 1, y' = y, and z' = z. Since k+1 is divisible by 6, we can add one more 6 to the expression.
Case 2: k+1 is divisible by 9
In this case, we can express k+1 as:
(k+1) = 6x' + 9y' + 20z' + 15
where x' = x, y' = y + 1, and z' = z. Since k+1 is divisible by 9, we can add one more 9 to the expression.
Case 3: k+1 is not divisible by 6 or 9
In this case, we can express k+1 as:
(k+1) = 6x' + 9y' + 20z' + 15
where x' = x + 2, y' = y + 1, and z' = z - 1. By adding 26, 19, and subtracting 1*20, we can obtain k+1.
Thus, we have shown that for each natural number n > 43, we can write n = 6xn + 9yn + 20zn + 15, where xn, yn, and zn are nonnegative integers.
Now, let's prove that 43 cannot be written in this form. If we assume that 43 can be expressed as:
43 = 6x + 9y + 20z + 15
Simplifying the equation:
28 = 6x + 9y + 20z
Considering the equation modulo 3, we have:
1 ≡ 0 (mod 3)
This is a contradiction since 1 is not congruent to 0 modulo 3. Therefore, 43 cannot be written in the given form.
In conclusion, we have proven by strong induction that for each natural number n > 43, we can express it as n = 6xn + 9yn + 20zn + 15, where xn, yn, and zn are nonnegative integers. Additionally, we have shown that 43 cannot be written in this form.

What is a linear equation?In mathematics, a linear equation has become one that takes the form y=mx+b. The inclination is B, and the y-intercept is m. Since y and x are variables, the preceding clause is frequently referred by the term a "linear equation involving two variables."
Bivariate linear equations are linear equations with two variables. Linear equations can be found in many places, including 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. When the formula has the structure y=mx+b, where m denotes the slope and b the y-intercept, it is often referred to because of being quadratic.A mathematical equation is said to be linear if its solution has the form y=mx+b, where m stands for the slope and b for the y-intercept.
To show that 3y² - 10y - 24y¯47 = O, we need to find constants C and k such that |3y² - 10y - 24y¯47| ≤ C|y| for all y > k.
3y² - 10y - 24y¯47 ≤ 3y² + 10|y| + 24
3y² + 10|y| + 24 ≥ 3y² - 10y - 24y¯47 for y ≥ 5
C = 6:
|3y² - 10y - 24y¯47| ≤ 6|y| for y ≥ 5
3y² - 10y - 24y¯47 = O.
b) Using the result from part a), we can rewrite the simultaneous equations as:
3y² - 10y - 24y¯47 = O
y - 2x = 4
y = 2x + 4
3(2x + 4)² - 10(2x + 4) - 24y¯47 = O
12x² - 8x - 79 = O
x = (8 ± √(8² + 41279))/24
x ≈ 3.1 or x ≈ -1.9
y ≈ 10.2 or y ≈ 0.2

Elmer spent the day at the mall. First, he bought five rabbits for $10 each. Later, he bought four cupboards for $70 each. After that, he found a twenty dollar bill. Also, he returned one rabbit. Write the total change to Elmer's funds as an integer.
Answers
Answer:
-300
Step-by-step explanation:
Step 1: Find the amount Elmer's funds decreased after purchasing the rabbits:
Let x represent Elmer's funds.
Since Elmer bought five rabbits for $10 each, he lost $10 5 times.
x - (10 * 5)
x - 50
Thus, Elmer lost (spent) $50 for the 5 rabbits.
Step 2: Find the amount Elmer's funds decreased after purchasing the cupboards:
Since Elmer bought four cupboards for $70 each, he lost $70 4 times:
x - (50 + (70 * 4))
x - (50 + 280)
x - 330
Thus, after purchasing the rabbits and cupboards, Elmer lost $330.
Step 3: Find the amount Elmer's funds increased after finding the twenty-dollar bill:
Since Elmer found a twenty-dollar bill, he gained $20
x - (330 + 20)
x - 310
Step 4: Find the amount Elmer's funds increased after returning one rabbit:
Since Elmer returned one rabbit, he gained $10:
x - (310 + 10)
x - 300
Thus, Elmer's funds changed totally by -$300.
Putting all the information together, we have:
x - 10 - 10 - 10 - 10 - 10 - 70 - 70 - 70 - 70 + 20 + 10
x - 50 - 280 + 30
x - 330 + 30
x - $300

Exponential of 1 is equal to the number itself which means 1.
Exponent is usually described as the method of demonstrating large numbers in terms of powers. It means, exponent refers to the count, that how many times a number is multiplied to itself to calculate that exponent.
In accordance with the exponent rule, any number raised to power of 1 would always be equal to 1 that is because it doesn't matter how many times we multiply 1 to itself. It is going to yield 1. For example, multiplying 1 hundred times i.e. 1^100 also results in 1.

What is compound interest?A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.
We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
Hannah contributes £750 and following 4 years has £844.13. Then the compound interest rate is given as,
844.13 = 750 (1 + r)⁴
(1 + r)⁴ = 1.1255

A single pump can add only 0.35 pound of air into a bicycle tire. The bicycle tire will hold a maximum of 640 ounces of air per square inch. How many pumps are required to inflate the bicycle tire to maximum pressure?
A.15 pumps
B. 115 pumps
C. 225 pumps
D. 1,829 pumps
Answers
The bicycle tire needs an amount of 115 pumps to be fully inflated. (Correct choice: B)
How many pumps are required to inflate the bicycle tire to maximum pressure
In this problem we need to determine the number of pumps needed to inflate the bicycle tire at maximum pressure, this number (n) is equal to the maximum capacity of the tire (V), in ounces, and the mass added by a single pump (p), in ounces:
n = V / p
If we know that V = 640 oz and p = 5.6 oz (1 lb = 16 oz), then the number of pumps is:
n = 640 oz / 5.6 oz
n = 114.286
n = 115
An amount of 115 pumps are needed to inflate the bicycle tire to maximum pressure.

Answer:
Jamal's age = 2×x+12= 2x+12
sum og ages = 45
2x+12+x= 45
=3x+12=45
=45-12= 3x
= 32=3x
x= 32/3= 10.67
2x+13 =21.34+12= 33.34
