-1.4335
Step-by-step explanation:
Subtract 13 from both sides
-5x = -17 - 13
Simplify -17 - 13 to -30
-5x = -30

Two negatives make a positive
x = 30/5
Simplify 30/5 to 6
<u>x = 6</u>

Answer:
It takes 50 minutes to paint the whole box
Step-by-step explanation:
1. Write an equation using equal fractions to represent this situation. Use a box to represent the total time it takes to paint the bookcase.
Wilson paints 40% of a bookcase in 20 minutes.
For the total box
40% = 20 minutes
100% = x
40 × x = 100 × 20
x = 100 × 20/40
x = 50 minutes
