B
5/4 times 4/5X=8/1 times 5/4
X=40/4
X=10
16 bc one side is 5ft so the other must be 3 to have an area of 15. Then 5+5+3+3= 16ft
Answer:
x=90-22
x=68
as the ray divide the right angle into 2
For the addition problem 1/4 would turn into 2/8 and the 3/8 would stay the same therefore it would be 2/8 + 3/8 =5/8. Then for the subtraction problem 1/4 would turn into 2/8 and 3/8 would stay the same therefore it would be 2/8 - 3/8 =1/8
