The formula for distance problems is: distance = rate × time or d = r × t
Things to watch out for:
Make sure that you change the units when necessary. For example, if the rate is given in miles per hour and the time is given in minutes then change the units appropriately.
It would be helpful to use a table to organize the information for distance problems. A table helps you to think about one number at a time instead being confused by the question.
The following diagrams give the steps to solve Distance-Rate-Time Problems. Scroll down the page for examples and solutions. We will show you how to solve distance problems by the following examples:
Traveling At Different Rates
Traveling In Different Directions
Given Total Time
Wind and Current Problems.
Price of 3 shirts=$18*3=$54
Price of 2 pair of socks=2*$3.99=$7.98
Price of a pair of slack=$45
Total amount- $54+$7.98+ $45-$106.98
Sales tax rate = 8.5%
8.5% of total amount-8.5% of $106.98=
(8.5/100)*106.98-9.0933
Total amount Rick paid=$106.98+9.0933=$116.0733

Answer:

Step-by-step explanation:
Multiply both sides by 7 to get rid of the denominator on the Right Side (RS). Do the same for the left side (LS) by multiplying both sides by 5 to get:

Simplify: 
Divide both sides of the equation by 7 to get: 
I thinks its 4.375 all u do is divide 35 by 8
Answer:
224 inches cubed.
Step-by-step explanation:
Because the area of a square is 16 square inches, the side length is 4 inches. This is because a square's formula for area is the side squared.
Since the box is 14 inches tall, we multiply 4 inches by 4 inches by 14 inches. This means the answer is 224 inches cubed.
We also notice we don't need a measurement for the base sides, we only need to multiply the area by the height.
