Question

Jill, Meg and Beth are sisters. Jill is 2 years younger than Meg. Beth is half as old as Meg. Let m represent Meg'a age. Write 2 other algebraic expressions based on the situation. Tell what each expression represents, and what the variable stands for in each expression. Please help form the expression. Thx

Answer 1

Meg --- m
Jill --- m-2
Beth = (1/2)(m)
= m/2 or
= (1/2)m

other possibly:

let Jill be x
Meg --- x+2
Beth --- (x+2)/2 or
= x/2 + 1 or
= (1/2)x + 1

try it by letting Meg = y
