11.2x+x+(x+8)=180
Combine like terms
3x+(x+8)=180
4x+8=180
180-8=172
4x=172
x=43

12.(x-3)+x+(x+8)+(x-5)=360
Combine like terms
4x-3+8-5=360
-3+8=5
5-5=0
4x=360
x=90

How can you find approximations of square roots?​
dem82 [27]

7c??? help on 7c???? please?!
Salsk061 [2.6K]
It would be a 12.5% increase. First you find her monthly wages: $10.50 x 160 hours= $1680 a month. Her insurance is $210/month. So you need to find what percentage 210 is of 1680. So 1680*x=210 . Solve for x by dividing 1680 on both sides and you get 0.125. Multiply by 100 to get the percentage and you get 12.5%. Check your answer by multiplying 1680 x 0.125 and you get 210.

Which is equivalent to sqrt x^10<br> A. X-5<br> B. X -1/5<br> C. X sqrt 10<br> D. X 1/5<br> E. X^5
Lesechka [4]
<h3>Answer:  E) x^5</h3>

\sqrt{x^{10}} = x^5

=====================================================

Explanation:

We simply take half of the exponent 10 to get 5. This applies to square roots only.

So the rule is \sqrt{a^b} = a^{b/2}

A more general rule is

\sqrt[n]{a^b} = a^{b/n}

If n = 2, then we're dealing with square roots like with this problem. In this case, a = x and b = 10.
