Answer:
x = 25
Step-by-step explanation:
Since we are trying to multiply 4 by x, we have to divide both sides by 4 to find x.
100 divided by 4 is 25, so x is 25.
To check your answer, we can multiply 4 by 25.
4 × 25 is 100
So, the answer is 25.
Answer:
2
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are points
Plug in the given points:
(y2 - y1) / (x2 - x1)
(12 - 4) / (6 - 2)
8 / 4
= 2
So, the slope of the line is 2.

Answer:
45°, 135°
Step-by-step explanation:
The total of the two angles is 1+3 = 4 times the smaller angle. The total is 180°, so the smaller angle is
180°/4 = 45°
The larger angle is 3×45° = 135°
The two angles are 45° and 135°.
