Answer 1

Hello there,

Determine which expression is equivalent to 3/4 - x ( 1/2 - 5/8) + ( -3/8x )

Answer: D. 3/4 - 1/4x

Answer 2

D

Explanation:

Using order of operations, distribute x into the parenthesis. Then convert to common denominators and move left to right simplifying. This will give:

`(3)/(4)-(1)/(2)x+(5)/(8)x-(3)/(8)x\\\\(3)/(4)-(4)/(8)x+(5)/(8)x-(3)/(8)x\\\\(3)/(4)+(1)/(8)x-(3)/(8)x\\\\        (3)/(4)-(2)/(8)x\\\\  (3)/(4)-(1)/(4)x`
