Answer:
13
Step-by-step explanation:
2(x-1)+8=4x-20
distribute 2
2x-2+8=4x-20
2x+6=4x-20
subtract 2x from both sides
6=2x-20
add 20 to both sides
26=2x
divide both sides by 2
x=13

Answer:
0.03865
Step-by-step explanation:
Since the true density for the two types of trees are given, we would evaluate the average for both of them
Low percentage of juvenile wood density = 0.523 and 0.0543
Average density = 0.523 + 0.0543/2
Average density = 0.55015
Moderate percentage of juvenile wood density = 0.489 and 0.0450
Average density = 0.489 + 0.0450/2
Average density = 0.5115
Therefore, difference in true average density for the two woods are = 0.55015 - 0.51150
= 0.03865
A triangle always adds up to 180 degrees total. Therefore the triangle is 70 + 26 + C = 180. Solving for C you would get 84 degrees.
