Question

It takes a company 4 hours to build 1,300 cell phones. If the company continues working at the same rate, how many hours will it take them to build 30,000 cell phones?

Answer 1

I need help with these two multistep equation word problems. please show work for them:

1. the measure of an angle is 34 degress less than its supplement. Find the measure of each angle.

2. The measure of an angle is 9 degress more than twice its complement. Find the measure of each angle.

Answer 2

T=30,000phones * 4h/1300phones=92.3 h.

1. A = X Degrees, B = (X-34) Degrees.
Supplementary angles are angles whose sum is 180o:

x + (x-34) = 180.
X = ?.
X-34 = ?

2. A = X Degrees, B = (2x+9) Degrees.
x + (2x+9) = 90o.
X = ?
2x+9 = ?
