A laundry service charges their customers 7fortheserviceand1.50 for each pound of laundry that needs to be cleaned. A customer's bill last month came to $12.25. How many pounds of laundry did the customer have for cleaning?

answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
