The height, h, of a cylinder is 5 units less than 3 times its radius, r. which expression represents the height of the cylinder in terms of its radius

h = height

r = radius

 3r = 3 times it's radius

5 units less means subtract so

h=3r-5

3r-5  

Step-by-step explanation:

we know the height of the cylinder is five units less which means h= -5, three times the radius would be 3r. Piece it all together and your answer is 3r-5

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
