Question

Ten times a number, x, is one-half the sum of the number and three.

Which answer represents this situation?

10x=1/2x+3

10x=1/2(x+3)

10x+1/2(x+3)

10x+1/2x+3

Answer 1

Given a number "x"
ten times this number is : 10x
one-half the sum of the number and three= 1/2(x+3)

Therefore:
The equation will be:
10x=1/2(x+3)

20x=x+3
20x-x=3
19x=3
x=3/19

Answer: the equation is : 10x=1/2(x+3) and the number is 3/19.

Answer 2

`10x=(1)/(2)(x+3)`

Explanation:

Let

x------> the number

we know that

The expression

"Ten times a number, x" ----->represent
`10x`

"one-half the sum of the number and three" ----->represent
`(1)/(2)(x+3)`

therefore

The complete expression represent

`10x=(1)/(2)(x+3)`
