Write an equation for the description.
Ten times the sum of half a number x and 7 is 9.

10( 1/2x + 7) = 9

Step-by-step explanation:

This is the answer because:

1) 10 times the sum is representing 10 multiplied by the sum of two numbers

2) The sum of half a number x and 7 is 1/2x + 7 because you have to figure out 1/2 of x first and then add it with 7

3) This whole entire expression is supposed to equal to 9, so the final answer is 10( 1/2x + 7) = 9

4) 1/2x + 7 is in parenthesis because you have to figure out the sum of those two number and then multiply it with 10

Hope this helps!
