<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division
A) If a number, n, divided by 8 equals 2.5, what is n?
n / 8 = 2.5
n = 8 x 2.5 = 20
B) The sum of a number, n, and 6.05 is 12.4. What is n?
n + 6.05 = 12.4
n = 12.4 - 6.05 = 6.35
C) Stacy is one-fourth as old as her mother. If Stacy's mother is
36, how old is Stacy?
(1 / 4) M
= S
S
= ( 36 / 4)
S
= 9 years
Therfore the answers are n = 20 ,n = 6.35, S
= 9 years
