Question

Amira is d years old.

a) Joshua's age is Amira's age divided by 5. Write
an expression in terms of d for Joshua's age.
b) An expression for Oliver's age is d + 7. Write a
sentence to describe how Oliver's age compares
with Amira's.

Answer 1

Oliver is 7 years older than Amira.

Explanation:

Amira: d

Joshua: d/5

Oliver: d + 7

if amira's age is "d" and oliver's age is "d + 7," that means you would add 7 to amira's age to get oliver's age. therefore, oliver is 7 years older than amira.
