Answer:
4m - 15
Step-by-step explanation:
a( x + y) = ax + ay
M=c/at
Divide both sides by a and t to isolate m. Then the solution is just m=c/at
Answer:
x = (125,0) y = (0,275)
Step-by-step explanation:
I think this is right, good luck!
Answer:
50 gallons 20%
50 gallons 30%
Step-by-step explanation:
If x is gallons of 20% moonshine, and y is gallons of 30% moonshine, then:
x + y = 100
0.20x + 0.30y = 0.25(100)
Solve the system of equations using substitution or elimination. Using substitution:
0.20x + 0.30(100 − x) = 0.25(100)
0.20x + 30 − 0.30x = 25
5 = 0.10x
x = 50
y = 50
