Answer 1

Let x be the number of months it will take for Jenny to grow her hair to 18 inches.
Given that the average hair grows at a rate of 1/2 inch per month, the equation can be written as:
12 + (1/2)x = 18.
Subtracting 12 from both sides of the equation, we get:
(1/2)x = 6.
Multiplying both sides of the equation by 2, to eliminate the fraction, we get:
x = 12.
Therefore, it will take Jenny 12 months to grow her hair to 18 inches.
