Wes can paint a certain room in 8 hours. Sally can paint the same room in 5 hours. How long will it take them working together t
lubasha [3.4K]

The time it takes them working together to paint the room is 3.08 hours

<h3>Rational expression</h3>

Rational expression are equation written as a ratio of two expressions or equations.

If Wes can paint a certain room in 8 hours, she can paint 1/8 of the room in 1 hr

Similarly, if Sally can paint the same room in 5 hours, , she can paint 1/5 of the room in 1 hr

Determine the time it takes them to paint the room altogether.

Time together = x

Using the expression below to determine the value of x

1/x = 1/8 + 1/5

1/x = 5+8/40

1/x = 13/40
x = 40/13

x = 3.08

Hence the time it takes them working together to paint the room is 3.08 hours

Tamiku [17]

Answer:

X=-12

Step-by-step explanation:

Subtract -5/2 on both sides:

X/3+5/2-5/2=-3/2-5/2

X/3=-8/2

X/3=-4

Multiply both sides by 3:

X/3*3=-4*3

X=-12
