Step-by-step explanation:

:)

x = 6 and y = -4

Here, we want to solve the systems of equation simultaneously using the elimination method

To use the elimination method in this case, we simply subtract the second equation from the first

Thus, we have it that;

To get x, we simply substitute y= -4 in any of the two equations

Answer:

y = -\(\frac{5}{6}\)x + 9

Step-by-step explanation:

0.5x + 0.6y = 5.4

0.6y = -0.5x + 5.4

Multiply 10 on all sides.

6y = -5x + 54

Divide 6 on all sides.

y = -\(\frac{5}{6}\)x + 9

Answer:

54

Step-by-step explanation:

Since diameter AB divides MN into two equal parts hence

MO = NO

NOW,

5x+34 = -2(1-7x)

5x+34 = -2+14x

34+2 = 14x-5x

36 = 9x

Dividing both sides by 9

x = 4

Now,

NO = -2(1-7(4))

NO = -2+56

NO = -2+56

NO = 54

Answer:

\( \boxed{ \bold{ \huge{ \boxed{ \sf{x = - 3 }}}}}\)

Step-by-step explanation:

\( \sf{ \frac{x}{ - 4} = \frac{3}{4} }\)

Do cross multiplication

\( \dashrightarrow{ \sf{x \times 4 = 3 \times ( - 4)}}\)

\( \dashrightarrow{ \sf{4x = - 12}}\) ( Multiplying a positive integer and negative integer gives a negative integer )

Divide both sides of the equation by 4

\( \dashrightarrow{ \sf{ \frac{4x}{4} = \frac{ - 12}{4} }}\)

Calculate

\( \dashrightarrow{ \sf{x = - 3}}\)

Hope I helped!

Answer:

a) 12

b) 129

Step-by-step explanation:

a)

\(w, x \in \mathbb{Z}_{\ge 0}\)

\(w>50\\x<40\)

For the smallest value of \(w-x\), we gotta figure out the smallest value for w and the highest value for x.

\(w>50 \Rightarrow \text{ smallest value is } 51\)

For \(x\), once \(-(-x)=x\), we conclude that \(x\) cannot be negative and therefore, \(x=39\).

\(51-39=12\)

b)

\(y, z \in \mathbb{Z}_{\ge 0}\)

\(y<70\\z\leq 60\)

For the largest value of \(y+z\), we gotta figure out the highest value for y and z.

\(y<70 \Rightarrow \text{ highest value is } 69\)

\(z\leq 60 \Rightarrow \text{ highest value is } 60\)

\(y+z=69+60=129\)

Answer:

Step-by-step explanation:

To compare these two values, we first need to convert the mixed number 7 3/8 to an improper fraction. To do so, we multiply the whole number (7) by the denominator of the fraction (8), then add the numerator (3), and put the result over the denominator:

7 3/8 = (7 x 8 + 3) / 8 = 59/8

Now we can rewrite the inequality as:

(59/8) × (4/5) < 59/8

To simplify the left-hand side of the inequality, we multiply the numerators and denominators:

(59/8) × (4/5) = (59 × 4) / (8 × 5) = 236/40 = 59/10

So the inequality becomes:

59/10 < 59/8

To compare these fractions, we need to find a common denominator. The least common multiple of 8 and 10 is 40, so we can convert both fractions to have a denominator of 40:

59/10 = (59 x 4) / (10 x 4) = 236/40

59/8 = (59 x 5) / (8 x 5) = 295/40

Now we can see that 236/40 < 295/40, which means that:

59/10 < 59/8

Therefore, the inequality 7 3/8 × 4/5 < 7 3/8 is true.

Answer:

  all are 60°

Step-by-step explanation:

The midpoints of the angle bisector and the foot of the median will lie on the midsegment of the triangle. In order for the foot of the altitude to lie on that same midsegment, the altitude must be a median.

If the angle bisector intersects the midpoint of the midsegment, it, too, is a median. The angle bisector will be a median only if the triangle is isosceles with the bisector's angle being the a.pex. The altitude will be a median only if the altitude's vertex is the a.pex of an isosceles triangle. Hence, the triangle must be equilateral, and all angles are 60°.

Answer:

3,600

Step-by-step explanation:

Answer:

Simplifying 9m + -3 + -7m = 0

Reorder the terms: -3 + 9m + -7m = 0

Combine like terms: 9m + -7m = 2m -3 + 2m = 0 Solving -3 + 2m = 0

Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right.

Add '3' to each side of the equation. -3 + 3 + 2m = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 2m = 0 + 3 2m = 0 + 3 Combine like terms: 0 + 3 = 3 2m = 3

Divide each side by '2'. m = 1.5

Answer:

Step-by-step explanation:

L=3W

P=2(L+W), given P=2 and L=3W we have

2(3W+W)=2

2(4W)=2

4W=1

W=1/4, since L=3W

L=3/4

So the side lengths are 1/4 ft by 3/4 ft

(or 3 in by 9 in)

The probability that either event A or B will occur is 43/60

Using the parameters given

n(A) = 29

n(B) = 14

Total number of events = 29+17+14 = 60

The probability of each event :

P(A) = 29/60

P(B) = 14/60

P(A or B ) = P(A) + P(B)

P(A or B ) = 29/60 + 14/60

P(A or B ) = 43/60

Therefore, the probability of A or B is 43/60

Answer: D

Step-by-step explanation:

If you owned this stock, you want a positive  slope because a positive slope increases the price as the number of hours increases

What is slope in this case?

The slope in this scenario is the change in stock price as result of the change in quantity of stocks sold, in other words, the slope in this stock case is -1.5, the integer beside the x, the  number of hours that have passed since the stock has been trading.

Note that the slope of -1.5 is negative, which means that as the number of trading hours increases, the stock price would go down, so if an investor intends to sell the stock at higher, the investor would a positive slope so that the price of stock increases.

Step-by-step explanation:

The range of whole numbers between which the decimal falls is 0 yards to 1 yard.

The whole number is set to positive integers including 0. i.e 0, 1, 2, 3, and so on.

To find the total amount of fabric Mary Beth needs to make a pillow, we first need to convert 7/12 yards into a decimal. To do this, we can divide the numerator by the denominator:

7/12 = 7 / 12 = 0.5833...

So, Mary Beth needs approximately 0.5833 yards of fabric to make a pillow.

To determine the range of whole numbers between which the decimal falls, we can round up to the next whole number (1 yard) and round down to the previous whole number (0 yards). Therefore, the range of whole numbers between which the decimal falls is 0 yards to 1 yard.

\(1\frac{3}{4}\) feet as a multiplication expression using the unit, 1 foot, as a factor is \(1\frac{3}{4}\)×1.

The given fraction is \(1\frac{3}{4}\).

\(1\frac{3}{4}\) feet can be written as a multiplication expression as follows: 1 foot × 1 3/4. This is because \(1\frac{3}{4}\) is the same as 1 + 3/4.

Furthermore, 3/4 can be written as 0.75, which is the same as 0.75 × 1 foot.

Therefore, the multiplication expression is 1 foot × \(1\frac{3}{4}\) = 1 foot × (1 + 0.75) = 1 foot × 1 + 1 foot × 0.75 = 1 foot + 1.75 feet.

Therefore, \(1\frac{3}{4}\) feet as a multiplication expression using the unit, 1 foot, as a factor is \(1\frac{3}{4}\)×1.

Step-by-step explanation:

To find out how many students took history and math, but not psychology, we need to first calculate how many students took history and math, and then subtract the number of students who took all three subjects.

From the given information, we know that:

24 students took history (including those who took history and math, and those who took all three subjects).

23 students took math (including those who took history and math, and those who took math and psychology).

26 students took psychology (including those who took all three subjects).

We also know that:

19 students took history but not math (including those who took history and psychology, but not math, and those who took only history).

11 students took math and psychology (including those who took only math and psychology, and those who took all three subjects).

10 students took history and psychology (including those who took only history and psychology, and those who took all three subjects).

2 students took all three subjects.

To find out how many students took history and math, we can subtract the number of students who took only history or only math from the total number of students who took history or math (including those who took history and math, math and psychology, and all three subjects):

Total number of students who took history or math = 24 + 23 - 2 = 45

Number of students who took only history or only math = 19 + (23-11) = 31

Number of students who took history and math = 45 - 31 = 14

To find out how many students took history and math, but not psychology, we need to subtract the number of students who took all three subjects (2) from the number of students who took history and math (14):

Number of students who took history and math, but not psychology = 14 - 2 = 12
