translate the following pharse into aĺgebraic equation. Five times the sum of a number and 8 equals 10.

Question

choices are

5×8=10

8x+5=10

5x+8=10

5(x+8)=10

Answer 1

Hi, Vicki.

First, we need to know that the sum is the answer to an addition problem. Since the answers options you have use the variable, x, we can translate the sum of a number and 8 to "x + 8".

Therefore, 5 times the sum of a number and 8 would be:

5(x+8)

Finally it says that this equals 10:

So,

5(x + 8)=10

Answer 2

5(x+8)=10

x+8 = 10/5 = 2

x =2-8 =-6

x=-6

5(-6+8) = 5(2) = 10

the number is -6
