Answer:

300, I think.

Answer:

there are 300 chapter books in the children's section

Step-by-step explanation:

the way you'd solve these kinds of problems is to turn it into an equation.

the ratio of 2:3 with a total of 500

becomes

2x + 3x = 500

2x + 3x = 500

combine like terms

5x = 500

divide both sides of the equation by 5

5x/5 = 500/5

x = 100

now, substitute x in the original equation.

2x + 3x = 500

200 + 300 = 500

There are 300 chapter books

Answer:

x² - 100

Step-by-step explanation:

Use the FOIL method. The FOIL method is the way in which you multiply the terms:

FOIL stands for First, Outside, Inside, Last. Multiply:

First:

x * x = x²

Outside:

x * 10 = 10x

Inside:

-10 * x = -10x

Last:

-10 * 10 = -100

Combine like terms:

x² + 10x - 10x - 100

x² + (10x - 10x) - 100

x² - 100

x² - 100 is your answer.

Answer:

y  = [tex]\frac{7}{6} x - 5[/tex]

Step-by-step explanation:

 Given expression:

        6x + 7y  = -42

To find an equation perpendicular to this, it implies the slope must be a negative inverse of the given one.

Solution:

Equation of any straight line is given as;

        y  = mx + c

where x and y are the coordinates

                m is the slope

                c is the intercept

Let us now find the slope of the line;

          6x + 7y  = -42

              7y = -6x - 42

   divide through by 7 to give;

             y = [tex]-\frac{6}{7} x[/tex] - 6

The slope is  [tex]-\frac{6}{7}[/tex]

     A line perpendicular will have a slope of a negative inverse;

          - ( [tex]-\frac{7}{6}[/tex] ) = [tex]\frac{7}{6}[/tex]

The answer is A.

Answer:

[tex]\huge\boxed{2x+3y<16}[/tex]

Step-by-step explanation:

The sum of 2x and 3y is less than 16

2x + 3y < 16

Answer:

2x+3y > 16

3y > 16-2x

y  > 16/3-2/3x

Answer: x= -10

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4.5(8−x)+36=102−2.5(3x+24)

(4.5)(8)+(4.5)(−x)+36=102+(−2.5)(3x)+(−2.5)(24)(Distribute)

36+−4.5x+36=102+−7.5x+−60

(−4.5x)+(36+36)=(−7.5x)+(102+−60)(Combine Like Terms)

−4.5x+72=−7.5x+42

−4.5x+72=−7.5x+42

Step 2: Add 7.5x to both sides.

−4.5x+72+7.5x=−7.5x+42+7.5x

3x+72=42

Step 3: Subtract 72 from both sides.

3x+72−72=42−72

3x=−30

Answer:

a) x = 60. b) b = 110. c) x = 20. d) x = 30.

Explanation:

For question a, 2x and 120° are opposite (vertical) angles so they must be the same measure according to the vertical angle theorem by definition, given they are angles formed by the transversal cutting two parallel lines. 2x = 120, so x = 60.

For question b, 130° and b + 20 are corresponding angles of the transversal cutting parallel lines, so they must be the same measure according to corresponding angle theorem(same side, one angle inner, and the other exterior of that) by definition. Given that they are both pairs of the same angle, they must be corresponding angles. 130° = b + 20, b = 110.

For question c, 120° and 2x + 20 are same side interior angles so they must be supplementary(add up to 180°) by definition. This is on the *same side* of the transversal inside the two parallel lines cut by it. 120° + 2x + 20° = 180°, x = 20°.

For question d, They are also on the same side but on the left so the same property of corresponding angles applies, so 3x + 10, and 100° must be the same measure. Therefore 3x + 10 = 100°, and x = 30.

Answer:

18=2x+7, The internship pays $5.50 an hour.

Step-by-step explanation:

The box on the far left is the amount the student is paid at their job, which is $18 an hour in this case. Solve 18-7 to get 11, then divide 11 by 2 to get the pay for the internship. To check your work, plug 5.50 into the equation.

18=2(5.50)+7

18=11+7

18=18

Answer:

The equation would be:

18 = 2x + 7

The internship pays $5.5 an hour

Step-by-step explanation:

18 - 7 = 2x

(Since we moved the 7 to the other side, in order to combine like terms)

11 = 2x

(Divide both sides by 2)

5.5 = x

(x = 5.5)

x would be the pay the internship pays an hour.

Answer:

Cost of chip cookies  = $17.5

Cost of ginger cookies  = $19.5

Step-by-step explanation:

Assume;

Cost of chip cookies  = c

Cost of ginger cookies  = g

So,

Maya's sales = 8c + 12g = 374 .....Eq1

Carlo's sales = 2c + 4g = 113 .......Eq2

4 x eq2

So

8c + 16g = 452......Eq3

Eq 3 - Eq 1

4g = 78

g = 19.5

and

c = 17.5

Cost of chip cookies  = $17.5

Cost of ginger cookies  = $19.5

Answer:

The difference quotient of f is 8. Option C

Explanation:

Difference Quotient

Given a function f(x), the difference quotient is defined as

[tex]\displaystyle d=\frac{f(h+h)-f(x)}{h},\ h\neq 0[/tex]

The function provided in the question is

[tex]f(x)=8x+1[/tex]

Find f(x+h) by substituting x by x+h:

[tex]f(x+h)=8(x+h)+1[/tex]

[tex]f(x+h)=8x+8h+1[/tex]

Now compute:

[tex]\displaystyle d=\frac{8x+8h+1-(8x+1)}{h}[/tex]

Operating:

[tex]\displaystyle d=\frac{8x+8h+1-8x-1}{h}[/tex]

Simplifying:

[tex]\displaystyle d=\frac{8h}{h}[/tex]

d=8

A.  Incorrect.

This choice is different from the answer.

B. Incorrect.

This choice is different from the answer.

C. Is correct

The difference quotient is 8 as explained above.

D. Incorrect.

This choice is different from the answer.

Answer: m<A = 35

Step-by-step explanation: The sum of the measures

of the interior angles of a triangle is 180°.

So we can setup the equation 3x + 5 + 8x + 65 = 180.

Combining our numbers and variables on the left, we have 11x + 70 = 180.

Now subtract 70 from both sides to get 11x = 110.

Dividing both sides by 11, we find that x = 10.

In the diagram, the m<A is represented as 3x + 5.

Plugging a 10 in for x, we have 3(10) + 5 or 30 + 5 which is 35.

So the m<A = 35.

Answer:

5x5=25

Step-by-step explanation:

5 x 5

= 5(1 + 0) x 5(1 + 0)

=5(1 + 1 - 1) x 5(1 + 1 - 1)

=5(2 - 1) x 5(2 - 1)

=(10 - 5) x (10 - 5)

=5 x 5 :0

=> 5 x 5 = 5 x 5 = 25

Answer: (b)

x g(x)

1 -16

2 -12

3 -8

If g(x) is 4*f(x), then we can find g(x) by multiplying 4 by x-5

g(x) = 4(x-5)

= 4x-20

Now we can plug in 1,2, and 3 for x to see which table makes sense.

g(1) = 4(1) - 20

= -16

g(2) = 4(2) - 20

= -12

g(3) = 4(3) - 20

= -8
