You can estimate 3.9 times 5.3 to 4 times 5 which is 20
so if the answer is around 20, you know that you will have exactly 2 digits before the decimal place
Let's solve your equation step-by-step.<span><span>−<span>5<span>(<span>x−4</span>)</span></span></span>=<span>−<span>30
</span></span></span>Step 1: Simplify both sides of the equation.<span><span>−<span>5<span>(<span>x−4</span>)</span></span></span>=<span>−30</span></span>
<span>Simplify: (Show steps)</span><span><span><span>−<span>5x</span></span>+20</span>=<span>−<span>30
</span></span></span>Step 2: Subtract 20 from both sides.<span><span><span><span>−<span>5x</span></span>+20</span>−20</span>=<span><span>−30</span>−20</span></span><span><span>−<span>5x</span></span>=<span>−<span>50
</span></span></span>Step 3: Divide both sides by -5.<span><span><span>−<span>5x</span></span><span>−5</span></span>=<span><span>−50</span><span>−5</span></span></span><span>x=<span>10
</span></span>Answer:<span>x=<span>10</span></span>

<h3>Trina uses 3.44 or
pints of white paint</h3>
<em><u>Solution:</u></em>
Given that,
Trina uses 8.6 pints of blue paint and white paint to paint her bedroom walls
3/5 of the amount is blue paint, and the rest is white paint
From given,
3/5 of 8.6 pints is blue paint
Thus, 2/5 of 8.6 pints is white paint
<em><u>How many pints of white paint did she use to paint her bedroom walls?
</u></em>
Thus she uses 3.44 or 17.2/5 pints of white paint
