1) Choice A. We can divide both sides by 5 to solve for x.
2) Choice A, yes.
Let’s divide both sides of the equation by 5.
5x=20
5x/5 = 20/5
x = 4
The equations have the same solution, so they are equivalent

Answer: 30
Step-by-step explanation:
3(0.3m + 6) + m =75
(0.3 x 3 = 0.9)
(6 x 3 = 18)
0.9m + 18 + m = 75
0.9m + m + 18 = 75
(m=1)
1.9m + 18 = 75
1.9m = 75 - 18
1.9m = 57
m = 57÷ 1.9
m = 30
Answer:
x = 30°
The angles:
- 2x° = 60°
- 3x° = 90°
- x° = 30°
Step-by-step explanation:
Hello!
The sum of all the angles in a triangle is 180°. So we can set up an equation for this question.
Solve the equation:
- 2x° + 3x° + x° = 180°
- 6x° = 180°
- x° = 30°
We can replace 30° for all the angles.
The measures are:
- 2(30°) = 60°
- 3(30°) = 90°
- 1(30°) = 30°
