If the difference in the side lengths of two squares is 10, and the sum of the side lengths is 18. what are the side of lengths?

14, 4

Step-by-step explanation:

Let's say the square side lengths are x and y. Then x-y=10 and x+y=18. Solve by solving for one variable then substituting into the other equation

x+y=18 so x=18-y

Substitute:

18-y-y=10

18-2y=10

18-18-2y=10-18

-2y=-8

y=4

Substitute y=4 back into the other equation.

x+y=18

x+4=18

x=18-4

x=14

1. You have that the speed is:

Where is the distance and is the time.

2. Tory pilots her boat before docking, therefore, his time is

3. Emilio continues for another , with a total of before docking. Therefore, his time is:

4. And his speed is:

5. Solve for and substitute the value into the formula of Tory's time:

The answer is:
