The sum of 8 and the quotient of a number and 5 is 15. Find the number.

Question

I don't know the answer , and I was just asking can someone work it out for me.

Answer 1

Let the number be "x"

The given problem thus translates to : 8 + (x/5) = 15

Subtracting 8 from both sides of the equation, x/5 = 7

Multiplying both sides of the equation by 5, (x/5) * 5 = 7*5

Simplify further on both sides to obtain x = 35

Answer 2

8+(n/5)=15

"The sum of" = You are adding something to...

"The quotient of a number and 5" = which means to divide a number by 5.

I called my unknown number "n."

So you add 8 to n/5. The parenthesis aren't really even necessary because order of operations will force you to divide before you add.
