Answer:
y= -7 and x= -1
Step-by-step explanation:
To do this, line up the variables so it looks like this...
y-6x=-1
y-3x=-4
The reason why -6x and -3y changes to negative is because that it moved to the other side of the equation.
distribute negative to the bottom equation because the two equations have the same number variable which is y...
y-6x=-1
-y+3x=4
Y cancels out and it will be left with -3x = 3.
X = -1.... plug that in to any of the two equation and you get y = -7.
Hope I helped and have a nice day!!
P = R - C
R - C = P
- C = P - R
Multiply both sides by - 1
-C*-1 = -1*(P - R)
C = -P + R
C = R - P
Answer:

Answer:
Pretty sure is 90 degrees
Step-by-step explanation:
If you need 300 bars per day, you need 2 cases per day (2*150 = 300).
Therefore you need 2*7 = 14 cases per week
You can subtract the case you already have leaving you with 13 cases needed
