Answer:
3x+2=16
Step-by-step explanation:
Answer: C)
Step-by-step explanation:
The inverse of an exponent is a square root And the inverse of addition is subtraction.
Solution1 Add <span>88</span> to both sides
<span>3x=10+8<span>3x=10+8</span></span>
2 Simplify <span>10+8<span>10+8</span></span> to <span>18<span>18</span></span>
<span>3x=18<span>3x=18</span></span>
3 Divide both sides by <span>33</span>
<span>x=\frac{18}{3}<span>x=<span><span>3</span><span><span>18</span></span><span></span></span></span></span>
4 Simplify <span>\frac{18}{3}<span><span>3</span><span><span>18</span></span><span></span></span></span> to <span>66</span>
<span>x=6<span>x=6</span></span>
Done
Check Answer ▲<span>3x-8=10<span>3x−8=10</span></span>
1 Let <span>x=6<span>x=6</span></span>
<span>3\times 6-8=10<span>3×6−8=10</span></span>
2 Simplify <span>3\times 6<span>3×6</span></span> to <span>18<span>18</span></span>
<span>18-8=10<span>18−8=10</span></span>
3 Simplify <span>18-8<span>18−8</span></span> to <span>10<span>10</span></span>
<span><span>10=10<span>10=10</span></span><span>

First, we converted each fraction into decimal numbers. You do this by dividing the numerator by the denominator for each fraction as illustrated below:
5/8 = 0.632/8 = 0.25
Then, we compared the two decimal numbers to get the answer.
0.25 is not greater than 0.63. Therefore, 2/8 is not greater than 5/8.
Plot 6 directly above 6. Plot root83 between 9 and 10 but nearer to 9 since its value in 3 significant figures is 9.11,
Plot root40 between 6 and 7 but nearer to 6 since its value in 3 significant figures is 6.32,
Plot root64 directly above 8 since 8x8=64,
And lastly plot 7.5 just in between 7 and 8,
Hope this helps ;)
