Answer:
(4, 3)
Step-by-step explanation:
Plug in x - 1 where y is. The equation will turn in 2x - 3(x - 1) = -1. Distribute, and you'll have 2x -3x + 3 = -1. Combine like terms (2x and -3x) and you'll have -x + 3 = -1. Subtract 3 from both sides, and you'll have -x = -4. Divide by -x (or -1) on both sides, and you'll have x = 4. Since y = x - 1, y = 3, since 4 - 1 = 3. Sorry if this sounds repetitive btw. Good luck :D
I don't think it can be reduced anymore.
The answer is 128......
if you expand them
-27 x -1024 x 216 divide by 216 x216
= -27 x -1024 divided by 216
-1024 x -1 divided by 8
= 1024 / 8
=128
Kevin will have enough. He will need to pay $23.10.
5% of $22 is $1.10.
22+1.10=23.10
23.10 is less than 24
