Answer:
4
Step-by-step explanation:
4 × 8 = 32
Divide each side by 8
4 × 8 /8= 32/8
4 = 32/8
The formula for an average of three numbers is (x+y+z)/3. So if V equals the average, then we find the formula
V = (x+y+z)/3
We are now looking for x. We can divide each of the variables in the parentheses by 3, making the formula
V = x/3 + y/3 + z/3
So now bring the unwanted variables to the same side as V.
V - y/3 - z/3 = x/3
Now multiply both sides by 3 to find x.
3V - y - z = x
x = 3V - y - z
If Ricky saves $7 a week, and there are 52 weeks in a year, you can estimate the amount of money he saves by multiplying 7 by 50, which will give you 350 dollars. So, saving $7 every week for 52 weeks will give you a little more than $350.

Step-by-step explanation:
Given
Required
Determine the equivalent of 1 mile/hour
Express 60 as 60 * 1
Divide both sides by 60
Reorder
Divide 88 by 60
Approximate to 3 significant figures
Hence;
1 mile/hour is equivalent to 1.47 feet/seconds
