2(4k+8)=10
8k+16=10 (she said 2k instead of 8k)
To continue solving, subtract 16 from both sides. That would give you 8k= -6. Then divide both sides by 8, and get -6/8 which equals -3/4.
Answer:
b = 20, c = 160
Step-by-step explanation:
b and 20 degrees are vertical angles, so they are equal.
b (20 degrees) and c are on a line together, so they add up to 180. 180 - 20 = 160 degrees

Answer:
<h3>x = 2log₂(3) - 1</h3>
Step-by-step explanation:
2ˣ⁺¹ = 9
x+1 = log₂(9)
x+1 = log₂(3²)
Transfer the power value inside the bracket and put it before the log.
x+1 = 2log₂(3)
<h3>x = 2log₂(3) - 1 </h3>
