Grace earns $5 each times she walks her neighbor's dog. She walks the dog 5 times in one week. Then she spends $7 on a book and $9 on a building set. Write an equation to represent how much money Grace has left, m.

$5 (5) - ($7+$9)=m

$25 - $16 =m

Step-by-step explanation:

$5 (5) - (7+9)=m

$25 - 16 =m

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
