Well... the segment FG = 4x + 3, the segment GH = 7x - 12, now, the
segment FH = FG + GH, those two fellows added up, and we know that FG and GH are both equal halves because G is the midpoint.
thus, FG = GH
or
and fairly sure, you know how much that is.

Answer:
323.2 revolutions (324 revolutions (rounded) )
Step-by-step explanation:
Savannah has to cover 1100 feet
Sarah has to cover 1100 feet
Now,
For Savannah:
diameter is 26 in, so radius will be 26/2 = 13 inches
Circumference (1 rev) =
There are 12 inches in 1 feet, so distance to be covered in inches:
1100 * 12 = 13,200 inches
Number of revolutions = 13,200/81.68 = <u>161.6 revolutions</u>
For Sarah, it is the same so:
161.6 revolutions
Together:
161.6 + 161.6 = 323.2 revolutions to cover the whole distance (both)
Rounded, it is About 324 revolutions
