Answer:
a. Sage and Tom have the same number of talk minutes left on their cell phone plans.
b. y = x - 7
Explanation:
Sage talked for 7 minutes with her dad.
Tom talked for 4 minutes with a friend and 3 more minutes with his mom which means he spoke for :
= 4 + 3
= 7 minutes
They both spoke for 7 minutes and therefore have the same amount of time left.
Algebraic expression:
Assuming the time Tom started with is denoted by x and the time he is left with is denoted by y.
The expression is:
y = x - 7
Answer:
12 inches
Step-by-step explanation:
A square has 4 sides with the same length.
The perimeter of a square is the 4 times the length of one side.
perimeter = 4s
perimeter = 4 * 3 inches
perimeter = 12 inches
