Reed is currently r years old. Which expression represents his age seven years from now
lyudmila [28]

Answer: r+7

Whatever his age is now, we add 7 to it. So we simply add 7 to r getting r+7.

Example: Say he is 10 years old now

r = 10

r+7 = 10+7 = 17

meaning he will be 17 seven years from now
