-208
Explanation:
If the complete expression is a³ – 6³
then a³ – 6³ with a being equal to 2 is
(2)³ – (6)³ =
(2 × 2 × 2) – (6 × 6 × 6)
=
(4 × 2) – (36 × 6)
=
(8) – (216)
=
-208
This is done with substitution, just do the arithmetic with 2 in the place of a.
<span>160 minutes.
The formula for Kristi's bill is (6.95 plus 0.07 per minute for a total of 18.15)
6.95 + 0.07m = 18.15
Subtract 6.95 from both sides
0.07m = 11.20
Divide both sides by 0.07
m = 11.20 / 0.07 = 160
So Kristi used 160 minutes.</span>
