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

Answer:
9.8w-7x+1
Step-by-step explanation:
9.8w-(7x-1)
Distribute the minus sign to each term in the parenthesis
9.8w-7x - -1
