<u>Answer:</u>
Two times the difference of a number x and 7 plus 10.
<u>Step-by-step explanation:</u>
We are to write a phrase which matches the following algebraic expression below:
![2 ( x − 7 ) + 1 0](https://tex.z-dn.net/?f=%202%20%28%20x%20%E2%88%92%207%20%29%20%2B%201%200%20)
We can see that there is a bracket with a coefficient outside it so we can express it as:
<em>'Two times the difference of a number x and 7'.</em>
While + 10 can be added to it to complete the phrase:
Two times the difference of a number x and 7 plus 10.
In order to solve this problem, we need to multiply 2/3 * 1 1/2.
![\frac{2}{3} *1 \frac{1}{2} =6/6=1](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B3%7D%20%2A1%20%5Cfrac%7B1%7D%7B2%7D%20%3D6%2F6%3D1)
