.9x-2.1+.9=.2(5-x) multiply .2(5-x)
.9x-2.1+.9=1-.2x; add - 2.1 + .9
.9x-1.2=1-.2x; cancel -2x by adding it by itself and add it on the .9x
1.1x-1.2=1; cancel -1.2 by adding it by itself and add it on the 1
1.1x=2.2; divide 1.1 so it can be canceled and then on 2.2
x=2 :)

Well assuming that the test is a 10 point test. 10 meaning one point each test he would get 30%
Answer:
Step-by-step explanation The apple juice is 30%and 3/10 of the proportion because:
when you add everything up: 25+30+45=100
now you must divide the whole cocktail just by the apple juice:
100 : 30 = 3.33333333
Meaning the apple juice takes 30% of the proportion. and 30% is 3/10
Rearrange into y=mx + b
So
-4x - 5y = -10 Add 4x to each side
-5y = 4x - 10 Divide each side by -5
y = 4x/-5 -10/-5 Simplify
y = -4x/5 +2
