Final answer:
To translate the sentence into an equation, use the variable J to represent Janelle's height. The equation is 72 = 12 + J. Solve for J to find Janelle's height.
Step-by-step explanation:
To translate the sentence into an equation, we can use the variable J to represent Janelle's height. The sentence states that 72 is the sum of 12 and Janelle's height. Therefore, the equation can be written as:
72 = 12 + J
This equation shows that the height of Janelle is equal to 72 minus 12. To find Janelle's height, we can simplify the equation by subtracting 12 from both sides:
J = 72 - 12
This can be further simplified to:
J = 60
Therefore, Janelle's height is 60 units.
