A is the correct answer coz if you substitute 22 in the place of X-5 the answer will be 17
Answer is 41 miles total
Equation is (2miles x 7) + (3 miles x 9) = total
14 + 27 = total miles
41 = total miles
My reasonable estimate might be about 2 1/2 feet. I know that because taking three rulers up to your bedroom or a normal room and get about 2 or 2 1/2 feet
8x+9-4x=25
4x+9=25
4x+9-9=25-9
4x=16
4x/4=16/4
X=4
If you substitute the -8 in for y you will get -72
You can then add the 72 to the other side and get -8x=64
Dividing by -8 to both sides to get x alone will give you x
X=-8
