Answer:
Step-by-step explanation:
∠CBA + ∠ABD = 180 {linear pair}
2x - 6 + x +1 = 180
3x -5 = 180
3x = 180 +5
3x = 185
x = 185/3
x = 61 2/3
10^ 7 = 10,000,000 which is 10 million
10^ 8 is 100 million
10^8 is closer, it is only 130 million away while 10^7 is 220 million away
−13=7y+64
Step 1: Flip the equation.
7y+64=−13
Step 2: Subtract 64 from both sides.
7y+64−64=−13−64
7y=−77
Step 3: Divide both sides by 7.
7y
7
=
−77
7
y=−11
