When 0.3(4x – 8) – 0.5(–2.4x + 4) is simplified, what is the resulting expression? I have 56 minutes and 10 questions left I need the answer fast I made a 2o on the first quiz whoops...

2.2x - 4.4

Step-by-step explanation:

0.3(4x-8) - 0.5(-2x+4)

1.2x-2.4-0.5 (-2x+4)

1.2x - 2.4 + x-2

2.2x - 4.4

Hope this helped :)

I think it's A= negative 4.4

Step-by-step explanation:

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510
