Answer:
v=2
Step-by-step explanation:
add five to the other side and: -8v=(-21+5)
divide -16 by -8: v= -16/-8
v=2
Call x the number of days the Alabama facility operares and y the number of days the Texas facility operates
Number of barrels produced:
Facility Alabama Texas total
HIgh grade production: 500x 600y 15,000
Medium grade production 200x 400y 8,400
Equations
500x + 600y = 15,000
200x + 400y = 8400
Divide each equation by 100
5x + 6y = 150
2x + 4y = 84
Multiply first by 2 and second by 5 =>
10x + 12y = 300
10x + 20y = 420
Subtract the first from the second:
20y - 12y = 420 - 300
8y = 120
y = 120/8
y = 15
Replace y value on any of the equations:
2x + 4y = 84 => 2x = 84 - 8y =
2x = 84 - 4(15)
2x = 84 - 60
2x = 24
x = 24/x
x = 12
Answer: the Alabama facility must operate 12 days and the Texas facility must operate 15 days.
Answer:
m=-3
Step-by-step explanation:
first multiply every thing out
3-18-4m=m
simplify
-15-4m=m
get all m's on one side
-15=5m
divide both sides by 5 to isolate m
-3=m
