Marry ann is 5 years younger than her friend. If the sum of their age is 61, how old is hef friend?
f-5 + f = 61
just find f.
oobleck is correct. Just find the missing variable's value. Simple. :)
To find out the age of Mary Ann's friend, we can first assign a variable to represent the friend's age. Let's call it "x".
Since Mary Ann is 5 years younger than her friend, her age can be represented as "x - 5".
The sum of their ages is given as 61, so we can set up the equation:
(x - 5) + x = 61
Simplifying the equation:
2x - 5 = 61
Add 5 to both sides:
2x = 66
Divide both sides by 2:
x = 33
Therefore, Mary Ann's friend is 33 years old.
