Gerrelle walks 4 days for a walk-a-thon. At the end of the walk-a-thon he walked 52 mles. Write and solve an equation to determine how much he walked each day. 4x = 52
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
Walk-a-thon
total time = 4 days
total distance = 52 miles
equation distance per day = ?
Step 02:
x = distance per day
\(x\text{ = }\frac{total\text{ distance}}{\text{total time}}=\frac{52\text{ miles}}{4\text{ days}}\)x = 52 / 4
x = 13 miles / day
The answer is:
The equation is x = 52 / 4, he walked 13 miles per day.

Answer:
x = x +1
Step-by-step explanation:
For the "no solution" case, we usually want a linear equation that resolves to something of the form 0 = 1. We can multiply this by any (non-zero) factor we may like, and add any linear expression that seems suitable. The simplest treatment would be to simply add x to both sides:
x +0 = x +1

Two people are playing the game rock, paper scissors. In each round both players show rock, paper, or scissors at the same time. What is the probability that both players show rock in the first round. Show your work.
The probability that both players show rock in the first round is 1/9 or 0.1111 (rounded to four decimal places).
In rock, paper, scissors there are three possible outcomes for each player: rock, paper, or scissors. Assuming both players choose randomly and independently of each other, each player has a 1/3 chance of showing rock in the first round.
To find the probability that both players show rock in the first round, we can use the multiplication rule of probability for independent events. The multiplication rule states that the probability of the intersection of two independent events is the product of their probabilities.
Therefore, the probability that both players show rock in the first round can be calculated as follows:
P(both show rock) = P(player 1 shows rock) x P(player 2 shows rock) P(both show rock) = 1/3 x 1/3 P(both show rock) = 1/9
So the probability that both players show rock in the first round is 1/9 or approximately 0.111.

Answer:
45.3 miles/h
Step-by-step explanation:
let 'x' be the speed of the car.
60 × 2/3 = 120/3 = 40
30 × 1/5 = 151/5
151/5 /40 = x / 60
151 / 200 = x / 60
=> x = (151×60) / 200

The opposite sides of a parallelogram have equal lengths.
- Opposite angles are congruent:
The opposite angles of a parallelogram have equal
Now,
a)
Opposite angles are congruent:
So,
5x + 29 = 7x - 11
29 + 11 = 7x - 5x
40 = 2x
2x = 40
x = 40/2
x = 20
And,
3y + 15 = 5y - 9
15 + 9 = 5y - 3y
24 = 2y
y = 24/2
y = 12
b)
Opposite sides are congruent:
So,
-6x = -4x + 6
-6x + 4x = 6
-2x = 6
x = -3
And,
7y + 3 = 12y - 7
12y - 7y = 3 + 7

Answer:
y \(\leq\) 4,
y ∈ [-∞, 4]
Step-by-step explanation:
Remember, the range of the function is all possible output values or y values.
As per the graph, it appears that the output, the y value, is less than or equal to 4. Hence:
y \(\leq\) 4
or
y ∈ [-∞, 4]
is the range, both are the same, they are just different ways of writing it.
find the sum of the values of a and b such that f(x)=2ax^2+bx+3 has a relative extremum at the point (-1,2)
the sum of the values of a and b such that f(x) = \(2ax^2 + bx + 3\) has a relative extremum at the point (-1,2) is 2.5.
If the function f(x) = \(2ax^2 + bx + 3\) has a relative extremum at the point (-1,2), then the derivative of the function must be zero at x = -1. This is because at a relative extremum, the slope of the tangent line is zero.
So, we need to find the derivative of f(x) and set it equal to zero at x = -1:
f'(x) = 4ax + b
f'(-1) = 4a(-1) + b = -4a + b = 0
Solving for b, we get:
b = 4a
Now, to find the sum of a and b, we just need to substitute b = 4a into the expression for f(x) and use the fact that f(-1) = 2:
f(x) = \(2ax^2 + bx + 3\)
f(-1) = \(2a(-1)^2 + b(-1) + 3 = 2\)
Substituting b = 4a, we get:
2a(1) - 4a + 3 = 2
2a - 4a + 3 = 2
-2a = -1
a = 1/2
Then, using b = 4a, we get:
b = 4(1/2) = 2
So, the sum of a and b is:
a + b = 1/2 + 2 = 2.5
Therefore, the sum of the values of a and b such that f(x) = \(2ax^2 + bx + 3\)has a relative extremum at the point (-1,2) is 2.5.

What is equation?A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

How to determine the value of a₄ of the sequence?From the question, we have the following definition of the function that can be used in our computation:
a₁= 3
aₙ = (aₙ₋₁)² + 4
The above definitions imply that we simply square the previous term and then add 4 to the squared result to get the current term
Using the above as a guide,
so, we have the following representation
a₂ = (3)² + 4
a₂ = 13
Also, we have
a₃ = (13)² + 4
a₃ = 173

At a university with 1,000 business majors, there are 200 business students enrolled in an introductory statistics course. Of these 200, 50 are also enrolled in an introductory accounting course. There are an additional 250 business students enrolled in accounting but not enrolled in statistics. If a business student is selected at random, what is the probability that the student is not enrolled in accounting?
Answer:
The probability to not to enroll in accounting = 70%
Step-by-step explanation:
Total business students = 1000
Stats students = 200
Students with stats and accounts = 50
So, only stats student = 200 – 50 = 150
Only accounts students = 250
The probability of students not enrolled in accounting will be the probability to enrolled in stats.
Total accounts students = 50+ 250 = 300
Probability of accounts students = 300 / 1000 = 0.3 or 30 %
So, probability to not accounting student = 100% - 30% = 70%
Walmart was having a sale on video games. They offered a 15% discount on a game that was originally priced at $30. After the sale, the discounted price of the game was increased by 10%. What is the new price of the game after this increase?
Answer:
28.05$
Step-by-step explanation:
The game got a discount of 15%.
New price is (30$) ( 0.85 ) = 25.5$ (since the discount is 15% you only pay for the 85% of the original price)
Then an increase of 10%. this is:
New price: 25.5$ (1.10) = 28.05
New price is 28$ with 5 cents
