The equation can be used to find the time in hours,
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 :

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,
and the time will be 2.5 hours. So the correct answer is option A.

Answer:
6
Step-by-step explanation:
I’m pretty sure it’s x=80? it seems like x+30 has to equal 110 and 80+30=110.
Answer:
m∠J =90°
m∠O = 140°
Step-by-step explanation:
We see here angle J having 90°, pure right angle shape.
m<J=90
Then we find the total interior angle using (n-2)*180
(4-2)*180
360°
So, m∠O = 360° - m∠J - m∠E -m∠K
m∠O = 360° - 90° - 80° -50°
m∠O = 140°
1.530 divided by 10 is your answer
