5v - 4/10 = 4/5
5v = 4/5 + 4/10 = 6/5
v = (6/5)/5 = 6/25
By simplifying the expression we get
1.7
108/12=9
(You have to divide because you are seeing how many times 12 will go into 108 square feet)
The width of the door is 9 feet!
You can check your answer by multiplying 12 feet times 9 feet.
Your answer will be 108 ft squared! :)
So, the width of the door is 9 feet.
Hope I helped! :)
