Final answer:
To find Julie's height, we can set up the equation j * 9 = 126 and solve for j by dividing both sides by 9.
Step-by-step explanation:
To solve this problem, we can set up the equation: j * 9 = 126. Since we are looking for Julie's height, we can use the variable j to represent it. To find the value of j, we need to isolate the variable by dividing both sides of the equation by 9. So the equation becomes: j = 126 / 9. Simplifying the right side of the equation gives us: j = 14. Therefore, Julie's height is 14 units.
The product of Julie's height and 9 is 126. To represent Julie's height with a variable j, we can set up an equation: 9j = 126. Solving for j, we need to divide both sides of the equation by 9, which gives us j = 126 / 9. Therefore, Julie's height is j = 14.
