R-16=81 solve the equation

r = 97

Step-by-step explanation: To solve for r in this equation, we want to get r by itself on the left side of the equation.

Since 16 is being subtracted from r, to get r by itself, we need to add 16 to the left side of the equation. If we add 16 to the left side, we must also add 16 to the right side.

Notice that on the left side, -16 and +16 cancel each other out so we're simply left with r. On the right side, 81 + 16 is 97 so we have r = 97.

We can check our answer by substituting 97 back into the original equation.

So we have (97) - 16 = 81.

97 - 16 is 81 so we have 81 = 81 which is a true statement so our answer, r = 97, is correct.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
