To find miles per hour:
3 3/5 miles divided by 4/5 hour
3 3/5 = 5*3 + 3 = 18/5
18/5 divided by 4/5 equals
18/5 times 5/4
The fives cancel out, and we have 18/4 which reduces to 9/2 or 4 1/2 miles per hour :)

Answer:
last one
Step-by-step explanation:
The three consecutive sides are
x
x + 1
x + 2
Set up:
x + x + 1 + x + 2 = perimeter
Solve for x.
After finding x, substitute your value of x back into the three consecutive integers to find your answer.
Answer:
y = 2 (x + 1) or y = 2 + 2x
Explanation:
Move all terms that don't contain y to the right side and solve.
