Answer:
h = 1/2
Step-by-step explanation:
Step 1: Write equation
2.4(5h + 10) - 3 = 27
Step 2: Distribute
12h + 24 - 3 = 27
Step 3: Combine like terms
12h + 21 = 27
Step 4: Subtract 21 on both sides
12h = 6
Step 5: Divide both sides by 12
h = 6/12
Step 6: Simplify
h = 1/2
A^2 + b^2 = c^2
5^2 + 12^2 = c^2
c^2 = 25 + 144
c^2 = 169
c = 13cm
63 in 4.5 hours
63 divided by 4.5 is 14 so
14 MPH would be your answer
