Answer:
x = 2 and y = -2
Step-by-step explanation:
We must first eliminate the y-variable:
2x + 3y = -2
3x - 6y = 18
4x + 6y = -4
3x - 6y = 18
_________
7x = 14
x = 2
Since we know x=2, we plug that back into one of the original equations to find y:
2x + 3y = -2
2(2) + 3y = -2
4 + 3y = -2
3y = -6
y = -2
Therefore, x = 2 and y = -2
Answer:
63.2
Step-by-step explanation:
So, we can break this shape into 2 shapes. A trapezoid and a rectangle.
For the trapezoid, we can do the formula.
((2.8 + 7.2)4)/2 = 20
Next, we can do the rectangle.
6 x 7.2 = 43.2
Now we can add them up and get our final answer.
43.2 + 20 = 63.2
