Final answer:
To represent Holly's height using the variable h, the equation h - 24 = 60 can be used. Adding 24 to both sides of the equation, we find that Holly's height is h = 84.
Step-by-step explanation:
To represent Holly's height using the variable h, we can set up the equation h - 24 = 60. The variable h represents Holly's height, 24 represents the difference between her height and 60, and 60 represents the given difference. To solve for h, we can add 24 to both sides of the equation, which gives us h = 60 + 24. Simplifying this equation, we find that Holly's height is h = 84.
