Question

Translate and solve: seven greater than r is at most 91.

Answer 1

Hi there!

"AT MOST" can be denoted by the sign:

r + 7 ≤ 91

Or, r + 7 has to be LESS THAN or EQUAL TO 91.

We can solve using subtraction; subtract 7 from both sides:

r + 7 - 7 ≤ 91 - 7

r ≤ 84

Answer 2

`r\leq 84`

Explanation:

Let's write an inequality:

`7+r\leq 91\\Subtract \ 7 \ from \ both \ sides\\r\leq 84`
