Answer 1

-1.5(4-n)+2.8-1.5(4-n)+2.8


-3/2x(4-n)+2.8-1.5(4-n)+2.8
-3/2x(4-n)+14/5-1.5(4-n)+2.8
-3/2x(4-n)+14/5-3/2x(4-n)+2.8
-3/2x(4-n)+14/5-3/2x(4-n)+2.8



-1/10x(15(4-n)-28+15(4-n)-28)


-1/10x(60-15n-28+15(4-n)-28)
-1/10x(60-15n-28+60-15n-28)

-1/10x(64-15n-15n)
-1/10x(64-30n)

-1/10x2(32-15n)

-1/5x(32-15n

Answer 2

Answer:

$3n-6.4$

Step-by-step explanation:

$-1.5(4-n)+2.8-1.5(4-n)+2.8$

Collect like terms:

$(-1.5(4-n)-1.5(4-n))+(2.8+2.8)$

Simplify:

$-3(4-n)+5.6$

Expand:

$-12+3n+5.6$

Collect like terms:

$3n+(-12+5.6)$

Simplify:

$3n-6.4$
