Answer 2

Which expression is equivalent to -
-1/5 (10x + 15) - 2?

A -2x – 1 -2 x – 1
B -2x – 4-2 x – 4
C -2x – 3-2 x – 3
D -2x – 5

Answer 3

The expression -1/5 (10x + 15) - 2 can be simplified as follows:

-1/5 (10x + 15) - 2 = (-1/5)(10x) + (-1/5)(15) - 2 = -2x - 3 - 2

Therefore, the expression is equivalent to -2x - 5.

The correct answer is D.

Answer 4

Which expression is equivalent to 2/3 (4x - 9)?

D.8/3 (x - 12)

Answer 5

The expression 2/3 (4x - 9) can be simplified as follows:

2/3 (4x - 9) = (2/3)(4x) + (2/3)(-9) = 8/3x - 6

Therefore, the equivalent expression is 8/3x - 6.

The correct answer is:
D. 8/3 (x - 12)
