Thats what my Aunt said... Idk</span>
-8x - 2y = -10
8x + 2y = -6
the answer is no solution.
If you spend $6 for food, the. You have $14 left. You have enough for 56 tickets. If you’re trying to find out how much the tickets are a piece you would divide $14 by 56. This would mean the tickets are .25¢ a piece.
Not sure if that’s what you’re asking for, but hope it helps :)
Answer:
D. 220.16 Square feet
Step-by-step explanation: The shaded area is the space in the square not filled by the circle. So we need to find the area of the circle. The formula for area of a circle is 
. So we fill in this equation with the information we already know:
Simplify the exponents
Multiply
So now we know the area of the circle we have to find the area of the square because the circle is inside the square. It is a simple 
which is 1,024. Since we are looking for the shaded area we will subtract the area of the circle from the area of the square because the circle is not shaded.
1024-803.94= 220.16 square feet
Answer:
x = -1
Step-by-step explanation:
3x + 7 = -x + 3
4x + 7 = 3
4x + 4 = 0
x + 1 = 0
x = -1
