Answer:
2.8 gallons 0.5% milk
4.2 gallons 3% milk
Step-by-step explanation:
let 'x' = .5% milk
let 'y' = 3% milk
System of Equations:
x + y = 7
.005x + .03y = 7(.02)
I used the substitution method and solved the first equation for y: y = 7 - x
.005x + .03(7 - x) = .14
.005x + 0.21 - .03x = 0.14
-0.025x + 0.21 = 0.14
-0.025x = -0.07
x = 2.8
7 - 2.8 = 4.2
y = 4.2
Answer:
Solve for z by simplifying both sides of the equation, then isolating the variable.
Exact Form:
z = 63/2
Decimal Form:
z = 31.5
Mixed Number Form:
x = 31 1/2
12 / 3 so the answer would be 4
