Answer:
Option A
Step-by-step explanation:
x + 8 = -3
x + 8 - 8 = -3 - 8
x = - 11
Okay first you need to combine like terms together (3x and 1x)
7x + 4 = 5 + 4x
now you need x only on one side, you could subtract either 7x or 4x
3x + 4 = 5
subtract 4 over
3x = 1 is the answer
Answer:
18x-16
Step-by-step explanation:
expression: (11x-8)+7(x-1)
ok so what you want to do is combine like terms
but first you are going to distribute
(11x-8)+(7x-8) you distribute the 7
they you can subtract 8 from -8 and that will give you -16
you will then add 11x and 7x which will get you 18x
the final expression will be 18x-16
Answer:
D
Step-by-step explanation:
Table D is the only one that pairs a quarter with every other available coin. It follows on by doing the same with the dime and with the nickel. Apparently, we're not interested in (dime, quarter) once we have identified (quarter, dime) as a possible outcome.
Answer:
x = 1 and y = 2
Step-by-step explanation:
because 100(1) + 50(2) = 100 + 100 = 200
