Round your answer to the nearest hundredth.<br><br> 13.48x − 200 < 256.12

wolverine [178]

Answer:

Step-by-step explanation:

13.48x − 200 < 256.12

Using the addition property , add 200 to both sides

That's

13.48x + 200 - 200 < 256.12 + 200

13.48x < 456.12

<u>Divide both sides by 13.48</u>

$\frac{13.48x}{13.48} < \frac{456.12}{13.48} \\ x < \frac{456.12}{13.48} \\ \: \: \: x < 33.83679$

We have the final answer as

x < 33.84 to the nearest hundredth

Hope this helps you
