On a 15-mile race, runners start with a 9-mile road race followed by 12 laps
around a track that is x miles long.
What is the length of the track? Write
and solve an equation.

When a formula is solved for a particular variable, several different equivalent forms may be possible. if we solved a=1/2bh for h, one possible correct answer is h=2a/b . which one of the following is not equivalent to this? a. h= 2(a/b) b. h= 2a(1/b) c. h= a/1/2b d. h= 1/2a/b

Eis the midpoint of line segment ac and bd also line segment ed is congruent to ec prove that line segment ae is congruent to line segment be

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.
