Answer:
x = −21.25
Step-by-step explanation:
0.4(-0.2x - 3) = 0.5
distribute the .4
.4 * -0.2 = -0.08x and 0.4 * -3 = −1.2
we now have -0.08x - 1.2 = 0.5
next we add 1.2 to both sides
-0.08x - 1.2 + 1.2 ( these two 1.2's cancel out ) = 0.5 + 1.2 ( 0.5 + 1.2 = 1.7)
we then have -0.08x = 1.7
We then divide both sides by -0.08
-0.08/-0.08 = x
1.7 / -0.08 = −21.25
we're left with x = −21.25
Answer:
They are equal.

I calculated 76 ÷ 12 and got 6.33333333333. (I think)
Answer:
See below
Step-by-step explanation:
The initial ordered-pairs are ![(x, y)](https://tex.z-dn.net/?f=%28x%2C%20y%29)
We have a rotation of 90 degrees counterclockwise with respect to origin
Note. Previously the points were
![A(-3, 4), B(-3, 0), C(-1, 3)](https://tex.z-dn.net/?f=A%28-3%2C%204%29%2C%20B%28-3%2C%200%29%2C%20C%28-1%2C%203%29)
After the rotation, we have
![A(-4, -3), B(0, -3), C(-3, -1)](https://tex.z-dn.net/?f=A%28-4%2C%20-3%29%2C%20B%280%2C%20-3%29%2C%20C%28-3%2C%20-1%29)
Thus, ![(x, y) \rightarrow (-y, x)](https://tex.z-dn.net/?f=%28x%2C%20y%29%20%5Crightarrow%20%28-y%2C%20x%29)
Then shifting horizontally to the right 2 units, we get ΔA'B'C'
Thus,
![(x, y) \rightarrow (-y, x) \rightarrow (x+2, y)](https://tex.z-dn.net/?f=%28x%2C%20y%29%20%5Crightarrow%20%28-y%2C%20x%29%20%5Crightarrow%20%28x%2B2%2C%20y%29)
Sum of all angles in any triangle is 180 degrees so,
X=180-66-90=24 degrees
