Question 15

Create an expression equivalent to 4(2x−1)+3(1/2x+5) that does not use parentheses.

Answer 1

9.5x + 11

Explanation:

First, distribute the 4 to (2x - 1) to get 8x - 4. Distribute 3 to (1/2x + 5) to get 3/2x + 15. Put them back together to get 8x - 4 + 3/2x + 15. Combine like terms to get 9.5x + 11.

Answer 2

Explanation:

8x - 4 + 1.5x + 15

8x + 1.5x = 9.5x

-4 + 15 = 11

9.5x + 11

Expression = 9.5x + 11

Without Simplifying = 19/2x + 11
