Step-by-step explanation:
42+5x+7x+6=180 (sum of angles in straight line is 180)
- 48+12x=180
- 12x=180-48
- 12x=132
- x=132/12
- x=11
now m <CBE =7x+6=7×11+6=77+6=83
Answer:
x= 7/4
(in decimal form) x= 1.75
Answer:
Step-by-step explanation:

Answer:
m = -3 for the line 33x + 11y = 22.
Step-by-step explanation:
33x + 11y = 22
Change into y = mx + b form.
11y = -33x + 22
Divide both sides by 11.
y = -3x + 2
Since m is the slope in the equation y = mx + b, and -3 is taking the place of m in this equation, the slope of this line is -3.
