Solve for x 1) 2x + 5 = 30 - 3x 2) -4 (11x +2) = 80 3) 3x + 1 + 32 = 180

1 answer:

6 0

1) x = 5
2x + 5 = 30 - 3x
(+ 3x)
5x + 5 = 30
(- 5)
5x = 25
( / 5)
x = 5

2) x = -2
(-4 * 11x) + (-4 * 2) = 80
-44x - 8 = 80
(+ 8)
-44x = 88
( / -44)
x = -2

3) x = 49
3x + 33 = 180
(- 33)
3x = 147
( / 3)
x = 49

I hope this helps! The / symbol means divide by the way :)

Could someone explain and help

vichka [17]

Answer:

80°

Step-by-step explanation:

The sum of the two angles (red and blue) is 145°, so you have ...

(4x +5)° +(6x -10)° = 145°

10x = 150 . . . . . . . . divide by °, add 5, simplify

x = 15 . . . . . . . . . . . divide by 10

Then the measure of the angle of interest is ...

m∠XMN = (6x -10)° = (6·15 -10)° = 80°
