Answer:
Additive inverse of (5-6) is (6-5),
------------------------------
So:
(5-6)+(6-5)=0
5-6+6-5=0
5-6=-6+5
-------------------------
Left <--- -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6 ---> Right
Move 5 places to the right of -6 and you should land on -1.

20% of 70 plants:
"0.2 x 70 plants = 14 plants"

<em>Erin and Dan went shopping at their local store. Erin bought shirts that cost $12 each and spent $18 on accessories. Dan bought the same number of shirts as Erin for $16 each and spent $10 on accessories.
</em>
<em>If Erin and Dan were billed the same amount by the store, how many shirts did each of them buy?</em>
Here is my answer
Let x is number of shirts

ERIN 12x+18
DAN 16x+10
Equally Billed 12x+18=16x+10 <=> x = 2
so each of them buy 2 shirts
