A. 21 miles
You divide 2 into 32 and get 16, then you add 16 plus 14 subtract 9 and get 21
35
Step-by-step explanation:
x+55 + 90=180
x= 180-145
x=35
Answer:
r = 1
Step-by-step explanation:
slope = change in y / change in x, so:
change in y / change in x = 2/3
5 - r / 7 - 1 = 2/3
5 - r / 6 = 2/3

now solve this equation.
first, multiply both sides by 6 to get rid of the fraction:

subtract 5 from both sides

multiply both sides by -1
