Layna can paint a 350-square foot room in 4 hours. It takes Bebe 7 hours to paint the same room. Which equation can be used to f

ohaa [14]

The equation can be used to find the time in hours, $\dfrac{t}{4}+\dfrac{t}{7}=1$ and the time will be 2.5 hours. So the correct answer is option A.

<h3>What is an equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Layna can paint a 350-square-foot room in 4 hours.It takes Bebe 7 hours to paint the same room.

Let t be the total time taken by both to paint.They are completing 1 job so the equation will be :

$\dfrac{t}{4}+\dfrac{t}{7}=1$

Further solving it we get;

7 t + 4 t = 28

11t = 28

t = 2.5 hours.

Therefore the equation can be used to find the time in hours, $\dfrac{t}{4}+\dfrac{t}{7}=1$ and the time will be 2.5 hours. So the correct answer is option A.
