Answer:
y=(1/9)x+4
Step-by-step explanation:
x=3b
b=(1/3)x
y=2/6(1/3)x+4
y=(2/18)x+4
y=(1/9)x+4
First put everything into numbers:
30 tens = 300
3 tens = 30
3 tenths = 0.3
Substitute these values:
300 - 30.3
Solve:
269.7
Answer:
$ 0.08 cents per foot
Step-by-step explanation:
add all of the numbers then subtract by 58.35 and divide by 300 and remove the negative
In the x quarts of 2% fat milk, there is 0.02x quarts of fat.
in the y quarts of 4% fat milk there is 0.04y quarts of fat.
together, there is (x+y) quarts of milk, and 0.24 quarts of fat.
the equations are:
x+y=9
0.02x+0.04y=0.24
multiply the first equation with 0.02: 0.02x+0.02y=0.18
subtract this new equation from equaition 2 to eliminate x:
0.04y-0.02y=0.24-0.18
0.02y=0.06
y=3
x=9-3=6
x is twice as much as y.
He used twice as much as the 2% fat milk than the 4% fat milk.
so the first choice is the correct answer.
