(-4, 6), (0, 2), (4, -2) are all ordered pairs that have the sum as 2.
-4+6 is the same thing as 6-4 if there's more positive than negative
0+2=2 because 0 plus a number equals to that number
4-2=2 because you're adding a negative number with the positive number together to get the answer

Answer:
15 shirts.
Step-by-step explanation:
A 20% discount means you still pay 80% of the price.
x represents the number of shirts that can be bought.
(20 x (1-0.2) )x = 240 or (20 x .8)x = 240
16 x = 240
x = 240/16 = 15
Answer: 423
Step-by-step explanation:
1)
x+10<-7
bring 10 to the other side
x<-10-7
x<-17
2)
-3x-4>5
bring -4 to the other side
-3x>9
divide -3 at the other side, since it is negative it changes to less than
x<-3
Yes you can and you do that by multiplying $42×1.30=54.60 and then $54.60×1.25=68.25
