X + 18i is the final product
h =
multiply both sides by 2 to eliminate the fraction
2A = ( b + c)h
isolate h by dividing both sides by (b + c)
h =

Answer:
D. X=-3, y=4
Step-by-step explanation:
-2x+3y=18 equation 1
x=-y+1 equation 2
-2(-y+1)+3y=18 replace x value of equation 2 into equation 1
2y-2+3y=18
5y=20
y=4
solve for x by replacing y value into either equation.
x=-y+1
x=-4+1
x=-3
Answer:
The difference in the unit rates of the jars of peanut butter is 0.4.
Step-by-step explanation:
In order to find the unit rates, you have to divide each price for the amount of units purchased with that price, which is:
27.12/8=3.39
26.53/7=3.79
Now, that you have the unit rate for each case, you have to subtract 3.39 from 3.79 to find the difference in the unit rates:
3.79-3.39=0.4
According to this, the answer is that the difference in the unit rates of the jars of peanut butter is 0.4.
