Answer:

-0.8=-0.8

Step-by-step explanation:

We have been given that n=-2 verified as a solution to the equation 1.4n+2=2n+3.2.

As n=-2 is the solution for our given equation, so it will satisfy our equation.

Let us substitute n=-2 is our given equation.

1.4*-2+2=2*-2+3.2

-2.8+2=-4+3.2

-0.8=-0.8

Since the value of n satisfies our equation, therefore, last line of the justification will be -0.8=-0.8.

15 buckets have a volume of 15 * 80 cL = 120 cL

1 L = 100 cL

120 cL * (1 L)/(100 cL) = 1.2 L
