How many hours would someone who earns $7.75 per hour have to work to earn $224.72

29 hours

Step-by-step explanation:

Let h represent the number of hours worked. Then wages paid for that time are ...

.. 7.75h = 224.72

Dividing by the coefficient of h lets us find its value.

... 224.72/7.75 = h = 28.996

Someone must work 29 hours at that rate to earn $224.72.

Comment on the answer

The given amount would be the gross pay for working that time period. In the real world, gross pay is rarely the same as net pay. Taxes and other deductions take their toll.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
