What I did is to add 0.52
+0.15
then try to find what could equal the same amount with 0.52
9514 1404 393
Answer:
- x +3x = 180
- x = 45 . . . . . . . choice C
- 3x = 135 . . . . . choice F
Step-by-step explanation:
Let x represent the measure of the original angle in degrees. Three times its measure is 3x. That will be the supplement if the sum of the two angles is 180°.
x + 3x = 180 . . . . . . . . . equation for finding the angle
x = 180/4 = 45 . . . . . . divide both sides by 4
3x = 3(45) = 135
The first angle is 45°. The second angle is 135°.
Answer:
What are the digits in the box?
Step-by-step explanation:
The only solution of the equation is x=0
X - 4 is not an equation because it does not have an equal sign.
