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
For the first one,
294 + 30 + x- 37 = 360
add like terms
287 + x = 360
subtract 287 from both sides
x = 73
for the second one
4x +3 = 63
subtract 3 from both sides
4x = 60
divide both sides by 4
x = 15

Answer:
x = 6
y = -9
Step-by-step explanation:
A.
Because in mathematics, a geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
