Adelivery person uses a service elevator to bring boxes of books up to an office. the delivery person weighs 150 lbs and each box of books weighs 50 lbs. the maximum capacity of the elevator is 1000 lbs. part a write an equation to represent this situation

1000 = 160 + 50x

1000 - 160 = 840

840 = 50x

840/50 = 16.8

he can bring up 16.8 approx., but total boxes would be 16.

Step-by-step explanation:

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
