Round your answer to the nearest hundredth.<br><br> 13.48x − 200 &lt; 256.12
wolverine [178]

Answer:

<h2>x < 33.84</h2>

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

Which of the following statements is true?
Semmy [17]

Answer:

Option B

Step-by-step explanation:

we know that

A <u>rational number</u> is one that can be represented as the ratio of two whole numbers

so

\frac{\sqrt{5}}{8} -----> Is not a rational number, because √5 is not a whole number, is a irrational number

\frac{\sqrt{4}}{9}=\frac{2}{9} ---> Is a rational number, because can be represented as the ratio of two whole numbers

therefore

√5/8 is irrational and √4/9 is rational
