It would be: -5(3x-9) = 2(x-63)-33
-15x + 45 = 2x - 126 - 33
-15x - 2x = -204
17x = 204
x = 204/17
x = 12
In short, Your Answer would be 12
Hope this helps!
Answer:
The third angle of the triangle is 70°.
Step-by-step explanation:
The two angles of a triangle (say Δ ABC) are given to be 30° and 80°.
We have to find the third angle.
Let us assume that ∠ A = 30° and ∠ B = 80°, then we have to find ∠ C.
Now, we know that, ∠ A + ∠ B + ∠ C = 180° {Property of a triangle}
⇒ 30° + 80° + ∠ C = 180°
⇒ ∠ C = 180° - 30° - 80° = 70°
Therefore, the third angle of the triangle is 70°. (Answer)
For a given x, the value on the blue line is about 1/2 the value on the black line. The appropriate choice is
y = (1/2)x
The answer is that the slope equals -2.
Explanation:
To find the slope, all you have to do is count how many units the line goes up and right between two points. Between points (-2,4) and (0,0), the lines does up -4 units (the negative means it went down) and right 2. Then, divide the up/down by the left/right, -4/2, in this case, to find the slope. -4/2 is -2. Therefore, the slope is -2.
