When 0.3(4x – 8) – 0.5(–2.4x + 4) is simplified, what is the resulting expressions
lisabon 2012 [21]

Answer:

2.4x-4.4

Step-by-step explanation:

Given the following question:

0.3(4x-8)-0.5(-2.4x+4)

To simplify the expression, we are going to need to rewrite the expression by expanding the terms and then solve by using the distributive property. Then we combine like terms in till the expression can no longer be simplified to find our answer.

0.3(4x-8)-0.5(-2.4x+4)
0.3(4x-8)
0.3\times4=1.2x
0.3\times4=2.4
1.2x-1.2-0.5(-2.4x+4)
-0.5(-2.4x+4)
-0.5\times-2.4=1.2
-0.5\times4=-2
1.2-2
1.2x-2.4+1.2x-2
1.2+1.2=2.4x
-2.4+-2=-4.4
=2.4x-4.4

Your answer is "2.4x - 4.4."

Hope this helps.

What is the equation of the line that passes through the point (6,-3) and has a<br> slope of – 3?
JulijaS [17]
(6,-3) m=-3
formula is y=mx+c
substitute: -3= 3(6)+c
-3=-18+c (takeaway 18 from both sides)
-15=c

Rewrite equation in form y=mx+c

Therefore answer is y=-3x-15

I think this is how u do it from what I can remember :)
