Question

the height of a cylinder is 5 units less than 3 times it’s radius, which expression represents the height of the cylinder in terms of its radius

Answer 1

Answer:

3r - 5 = h

Step-by-step explanation:

The statement basically says the equation, so all that is needed is interpretation. First, look at the "three times". If the height is just three times the radius, it will look like 3r = h, because if any number is put into r, then h will be three times larger. Then it says "5 units less", which can be put as r - 5 = h with the same logic as the previous explanation. Combining those two gives us, lo and behold, 3r - 5 = h.
