A (3110%, 325%, 314%, 313%) because it’s going from the biggest number on the left to the smallest number on the right.

you're given all those values, h,k and r, so just plug them in
Answer: BET!!!! I'll follow you fam!!!
Step-by-step explanation: Fank wou!!!
3x-12y = 5
-x+3y = 9
First step is to make the coefficient of either x or y same.
3x-12y = 5
(-x+3y = 9)3
3x-12y = 5
-3x+9y = 27
-4y = 32
y = -8
If we know that 6 things cost 2.99 and we want to know unit price we just have to divide 2.99 by 6.
So 2.99:6=0.49$ - its the result.
Now we can say that his sister is not correct, because price is different that 2$/unit.
