Note that if we add each side of the 2 equations, y will cancel out:
-12x-y+(17x+y)=6+4
5x=10
x=2
Substituting x=2 in either of the equations, we find the value of y.
Let's use the first equation:
-12x-y=6
-24-y=6
-y=24+6
-y=30, so y=-30.
Thus, the solution is (2, -30)
Answer: C
Answer:
6
Step-by-step explanation:
You have a total area of 2,200 sq units to cover... and each can of paint covers 400 sq units. So, you'll need:
2200 sq units / 400 sq units/can = 5.5 cans
In such problems, we always round up, since you will need 5 full cans of paint, and half of a 6th can.
So, in total you will need 6 cans of paint to cover all 2,200 sq units.
Answer:
1/2
Step-by-step explanation:
if you find the LCD of the numbers, you will find that it is 8. Then, you divide both of them by 8 and you get 1/2
Hope this helped a bit :)
Answer:
