Answer:

$15

Step-by-step explanation:

let the hourly rate of pay for Ben  = B

let the hourly rate of pay for Judy  = J

Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75;

              4J + B = 75 ----- i

Judy worked 2 hours and Ben worked 6 hours, their combined pay was $120

               2J + 6B  = 120 --- ii

Now, we should solve the expression;

   Multiply equation ii by 2 and equation i by 1;

            4J + B = 75 ----- i    x 1  ;    4J + B  = 75          -- iii

            2J + 6B  = 120 --- ii  x 2 ;   4J + 12B  = 240    ---iv

Now,

 equation iv - iii;

                   11B  = 165

                      B  = $15

So, solving for J;

          4J + B = 75

         4J + 15  = 75

          4J  = 75 - 15  = 60

          J  = $15

Answer:

[tex]m=0[/tex]

Step-by-step explanation:

Given the points

(-8,-3)and(-12,-3)

The slope between the points  (-8,-3) and (-12,-3) can be determined

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-8,\:-3\right),\:\left(x_2,\:y_2\right)=\left(-12,\:-3\right)[/tex]

[tex]m=\frac{-3-\left(-3\right)}{-12-\left(-8\right)}[/tex]

[tex]m=0[/tex]

Answer:

[tex]\angle FCB[/tex]

Step-by-step explanation:

Supplementary angles are angles that sum to [tex]180^{\circ}[/tex]. In this case, [tex]\angle FCB[/tex] is supplementary to [tex]\angle DCF[/tex] since they add up to the angle of a straight line which is [tex]180^{\circ}[/tex].

Hope this helps :)

There are endless possibilities for x, because 1 to the power of any x will always be 1.

Answer:

$77.76

Step-by-step explanation:

90 x .2 = 18 (20% off)

90 - 18 = 72 (sale price)

72 x .08 = 5.76 (tax price)

72 + 5.76 = 77.76 (total)

Answer: 60 shirts.

Step-by-step explanation: Camila: 40/hr Evelyn: 20/hr

20 + 40 = 60

Answer:

commercial =  9

movie = 5

Step-by-step explanation:

Step one:

let the number of commercials be x and movies be y

so

40x+130y=1010-------------1

since there are a total of 14 commercials and movies combined

x+y=14--------------2

Hence the systems of equation is

40x+130y=1010------1

x+y=14-------------------2

Step two:

from equation 2

x=14-y

substui]te the value of x in  equation 1

40(14-y)+130y=1010

560-40y+130y=1010

collect like terms

130y-40y=1010-560

90y=450

divide both sides by 90

y=450/90

y=5

movies is 90

put y=5 in equation 2

x+5=14

x=14-5

x= 9

commercial is 9 in numbers

and movie is 5

Answer:

Answer:

L = 2500/W

Step-by-step explanation:

Let the fields m be rectangular in nature

Area = LW

Perimeter = 2(L+W)

L is the length

W is the width

Given

Perimeter = 200ft

Area = 2500ft²

Substitute into the formula

200 = 2L+2W

100 = L+W ...... 1

2500 = LW.... 2

From 1; L = 100-W

Substitute into 2

2500 = (100-W)W

100W - W² = 2500

W²-100W+2500 = 0

W²-50W-50W+2500 = 0

W(W-50)-50(W-50) = 0

W - 50 = 0

W =50

Substitute w = 50 into LW = 2500

L = 2500/50

L = 50

Hence the equation that can be used to find the length of the field is

L = 2500/W

Answer:

It's 60

Step-by-step explanation:

All triangles angles have to add up to 180 degrees. 60 plus 60 plus 60 is `80.

Answer:

C. 120°

Step-by-step explanation:

Just by looking at it, you can see that it is over 90° which automatically makes it not 60° and your only option left is 120°

Answer:

-0.9

Step-by-step explanation:

0.6(x+2)=0.55(2x+3)

Use the distributive property to multiply 0.6 by x+2.

0.6x+1.2=0.55(2x+3)

Use the distributive property to multiply 0.55 by 2x+3.

0.6x+1.2=1.1x+1.65

Subtract 1.1x from both sides.

0.6x+1.2−1.1x=1.65

Combine 0.6x and −1.1x to get −0.5x.

−0.5x+1.2=1.65

Subtract 1.2 from both sides.

−0.5x=1.65−1.2

Subtract 1.2 from 1.65 to get 0.45.

−0.5x=0.45

Divide both sides by −0.5.

x= 0.45/−0.5

x= -0.9

Answer:

The length of AD is 70

Step-by-step explanation:

From the given figure

→ In triangle ADC

∵ EB // to DC

→ That means EB divides the sides AD and AC into parts proportional

∴ E divides AD into AE and ED

∴ B divides AC into AB and BC

∴ [tex]\frac{AE}{ED}[/tex] = [tex]\frac{AB}{BC}[/tex]

∵ ED = 60

∵ AB = 12

∵ BC = 72

→ Substitute them in the ratio above

∴ [tex]\frac{AE}{60}[/tex] = [tex]\frac{12}{72}[/tex]

→ By using cross multiplication

∵ AE × 72 = 12 × 60

∴ 72 AE = 720

→ Divide both sides by 72

∴ AE = 10

∵ AD = AE + ED

∴ AD = 10 + 60

∴ AD = 70

∴ The length of AD is 70

Answer:

g = 8

Step-by-step explanation:

first move 20 to the right side of the equation by subtracting it. so the equation becomes 0.25g= 22-20 --> 0.25 = 2 and then divide 2 by 0.25 and g will equal 8. you can also plug in 8 for g to check your answer.

Answer:

g = 8

Step-by-step explanation:

First we want to simplify the sides so we will subtract 20 fror each side

.25g =2

then we need to divide each side by .25 to get g isolated or by itself to find the answer

g = 8

If you plug it back into the equation it will be true

20 + (.25 * 8) = 22

Answer:

B (6:17)

Step-by-step explanation:

The values of red and white are 8 and 4, so you add them. The ratio should then be 12:34 because 34 is the total of all values. When simplified, 12:34=6:17

Answer:

im thinking c add them all together and you get that 17:6 if u kow how to add :^

Step-by-step explanation:

Answer:

a. 90 pizzas

b. 12% decrease

Step-by-step explanation:

To receive a bonus, there must be 20% increase in the number of pizzas

Thus;

20% of 75 = 20/100 * 75 = 1500/100 = 15

So the number of pizza to be sold to receive the bonus will be 15 + 75 = 90

So now, we have 66 pizza sold today;

We can see that there was a decrease from 75

Percentage decrease will be;

(new value - old value)old value * 100%

= (66-75)/75 * 100%

= -9/75 * 100%

= -0.12 * 100% = -12%

This shows a 12% decrease

Answer:

x = 12

Step-by-step explanation:

The consecutive angles in a parallelogram are supplementary, thus

7x - 12 + 108 = 180, that is

7x + 96 = 180 ( subtract 96 from both sides )

7x = 84 ( divide both sides by 7 )

x = 12

Answer:

B

Step-by-step explanation:

>60 means greater than 60

So the inequality would be 30 + 5x > 60

Answer:

0

Step-by-step explanation:

3x2.6x0=0

Answer:

infinite solutions

Step-by-step explanation:

Given

x + 3 + 2x = 4 + 3x - 1 ( simplify both sides )

3x + 3 = 3x + 3

Since the equation is the same on both sides.

This indications the equation has an infinite number of solutions
