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

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.
