Answer:

3(2x-2)-4(x+7)+20 = -8 => x = 13

Step-by-step explanation:

3(2x-2)-4(x+7)+20 = -8

6x-6-(4x+28)+20 = -8

6x-6-4x-28-20 = -8

6x-4x-6-28 = -8

2x- 34 = -8

2x -34 +34 = -8 +34

2x = 26

x= 13

*Awarding Brainliest to first responder with the correct answer!*<br><br> What is m∠CDJ ?

Bogdan [553]

Answer:

Step-by-step explanation:

Angle ADC and angle CDJ are complementary. That means that they add up to equal 90 degrees. Therefore,

4x + 3x - 8 = 90 and

7x = 98 so

x = 14

Sub in a 14 for x in 3x - 8:

3(14) - 8 = 34

Angle CDJ = 34 degrees

Step-by-step explanation:

$5x - 2y = 30$

$5(8) - 2(5) = 30$
