Expression: 3g+2
cost of 8 games: 3*8=24+2= 26
I think it would be 137.1, due to the total being 360. Just subtract.
Lets say that the first number is x and the second number is y.
from the question we know that:
y=-3x and x+y=-4
from there, you need to replace the y in the second equation with -3x since we know that is what y equals so we can have an equation with only one variable.
x+-3x+-4
Then you solve for x.
-2x=-4
x=2
then you find y with the fact that y=-3x
y=-6
Write it out then put put it as standard notation then multiply 7 with 30 and 5 then get answer and add it up and that would be ur final answer
