This is not a difficult question and I will help you solve it :)

When calculating 1/10 from 40, what we have to do is this:

(1/10) * 40 = 4

This means that we have to multiply 40 by 1 and divide by 10 :)

So the answer in this case is 4.

Solve: -rt - 80 > 30 for r. show your work!

<h2>Steps:</h2>

So to solve for a variable, we must isolate it onto 1 side of the inequality. In this case, we must isolate r. Firstly, add 80 to both sides of the inequality:

$-rt>110$

Next, divide both sides by t:

$-r>\frac{110}{t}$

Next, multiply both sides by -1. Since we are multiplying by a <em>negative</em> number, flip the inequality symbol as well:

$r$

<h2>Answer:</h2>

<u>In short, your final answer is $r$ </u>
