Let's call the number of months it takes for Jenny's hair to grow to 18 inches as "x".
Based on the given information, we know that Jenny's hair grows at a rate of 12 inches per month. So, in x months, Jenny's hair will have grown by 12x inches.
Now, our equation is:
12x + 12 = 18
To solve for x, let's subtract 12 from both sides of the equation:
12x = 6
Dividing both sides of the equation by 12, we find:
x = 6/12
Simplifying this, we get:
x = 1/2
So, it will take Jenny 1/2 month (or 2 weeks) to grow her hair from 12 inches to 18 inches. reword this
Jenny's hair grows at a rate of 12 inches per month. We want to find the number of months it takes for her hair to grow to 18 inches, which we'll call "x". In x months, Jenny's hair will have grown by 12x inches.
We can set up the equation: 12x + 12 = 18.
Next, let's subtract 12 from both sides: 12x = 6.
To solve for x, we divide both sides by 12: x = 6/12.
Simplifying this, we find: x = 1/2.
Therefore, it will take Jenny 1/2 month (or 2 weeks) to grow her hair from 12 inches to 18 inches.
