Which expression shows 0.5(x+3) written as a sum

0.5x + 1.5

To express 0.5(x+3) as a sum, we need to distribute the 0.5 to both x and 3 and then combine like terms.

First, multiply 0.5 by x:
0.5 * x = 0.5x

Next, multiply 0.5 by 3:
0.5 * 3 = 1.5

After expanding and distributing the 0.5, we have:
0.5(x+3) = 0.5x + 1.5

Therefore, the expression 0.5(x+3) written as a sum is 0.5x + 1.5.
