Answer:
x = 5
Step-by-step explanation:
9/15 = 3/x
x = 5
One mile equals 5,280 feet, therefore you would multiply 12 x 5,280 which is 63360 feet per hour.
the starting amount would be the 550, because it doesn't have a variable assigned to it.
change per week is 20 since it is being multiplied by the number of weeks
-4(x + 1) + 7x = 8
-4x - 4 + 7x = 8
3x - 4 = 8
3x = 8 + 4
3x = 12
x = 12/3
x = 4 <===
