You take 50/4 which equals 12.5
so now you say “well one sub is 2.95”
take that and multiply it by 12
12 x 2.95 = 35.4
then you take 2.95 and divide it by 2 that is 1.48
so now you take 35.4 + 1.48
the cost should be 36.88
So the equation is 2x + y = 9
you want to solve the equation so that y is on one side. in order to do this you need to subtract 2x from BOTH sides to get y by itself.
after, you should get y = 9 - 2x
40% of 270 is 108 because first you divide 40/100and you get 0.4 then you multiply that by 270 and you get 108
Answer:
Step-by-step explanation:
120 is going to be 45 + x.
120 - 45 = x
120 - 45 = 75.
