Jade is 9 years old. The sum of her parents age is the square of Jade's age Her father is 11 years older than her mother.
A) How old is Jade's mother?
mom ---- x
dad ------ x+11
Just translate "The sum of her parents age is the square of Jade's age " into math
x + x+11 = 9^2
solve for x
68
nope
x + x+11 = 9^2
2x + 11 = 81
2x = 70
x = 35
the mother is 35
check:
if the mother is 35, then dad is 46
the sum of their ages is 81 which is 9^2
answer of 35 is correct
To find out how old Jade's mother is, we need to solve the given information:
Let's assume Jade's mother's age is 'M'.
According to the problem statement, Jade's father is 11 years older than her mother, so Jade's father's age is 'M + 11'.
The sum of her parents' ages is the square of Jade's age, which is 9. So we can write the equation as:
M + M + 11 = 9^2
Simplifying the equation:
2M + 11 = 81
Subtracting 11 from both sides:
2M = 81 - 11
2M = 70
Dividing both sides by 2:
M = 70 / 2
M = 35
Therefore, Jade's mother is 35 years old.
