Question

Which equation is equivalent to the given expression? -(1/2y+1/4) A. -1/4(1+2y) B. 1/4(2y-1) C. -2(1/4y-1/8) D. 2(1/8-1/4y)

Answer 1

Answer:

A. -¼(1+ 2y)  

Step-by-step explanation:

                    -(½y + ¼)                 = -½y - ¼

                  -¼(1+ 2y) = -¼ - ½y = -½y - ¼

B is wrong. ¼(2y - 1)                   =  ½y  - ¼

C is wrong. -2(¼y - ⅛)                = -½y + ¼

D. is wrong. 2(⅛ - ¼y) = ¼ - ½y = -½y + ¼
