Question

When 4(0.5x + 2.5y - 0.7x - 1.3y + 4) is simplified, what is the resulting expression?
-0.8+4.8y+16
0.8x-4.8y+16
-0.8x-4.8y +4
0.8x+4.8y+4

Answer 1

Answer:

- 0.8x + 4.8y + 16

Step-by-step explanation:

Let us simplify the expression.

4 ( 0.5x + 2.5y - 0.7x - 1.3y + 4 )

= 4(0.5x - 0.7x + 2.5y - 1.3y + 4)

= 4(- 0.2x + 1.2y + 4)

= 4(- 0.2x) + 4(1.2y) + 4(4)

= {4×(- 0.2x)} + (4×1.2y) + (4×4)

= - 0.8x + 4.8y + 16

Hence the resulting expression will be -0.8x + 4.8y + 16

hope it helps.
