The solution is n = –2 verified as a solution to the equation 1.4n + 2 = 2n + 3.2. what is the last line of the justification?

 1.4n + 2 = 2n + 3.2

substitute the solution n = -2 into the equation 

 1.4n + 2 = 2n + 3.2

 1.4(-2) + 2 = 2(-2) + 3.2

-2.8 + 2 = -4 + 3.2

-0.8 = - 0.8 

n = -2 makes the equation becomes true

so

Yes, n = -2 is the solution of the equation

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

and that lightbulb changing party must be freaking lit!

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
