It takes Zion three times as long to paint a room as it does Sanjay. How long does it take each person by himself if they can paint the room together in 30 minutes?

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

ratio is 2 : 9

the answer is three

13.5 : 3
