Question

Eslynn tracked her speeds and times she cycled on the weekend.

Answer 1

Answer: 30

Step-by-step explanation:

Example

x=y

x+z=y+z

If we subtract the same number from both sides of an equation, both sides will remain equal.

Example

x=y

x−z=y−z

If we divide both sides of an equation by the same number, both sides will remain equal.

Example

x=y

x÷z=y÷z

If we multiply both sides of an equation  by the same number, both sides will remain equal.

x=y

x⋅z=y⋅z
