Answer:
X=3
Step-by-step explanation:
12x-31=5
12x - 31 - 31 = 5 + 31
12x = 26
12x / 12 = 26 / 12
x = 3
To solve the equation you take 31 to the right by subtracting it from the left then adding it to the right.
From there you divide each side by 12

Answer:
The book was marked up 150 percent.
Step-by-step explanation:
The angles all form vertical angles. The ones labeled are vertical to each other and the ones not labeled are vertical to each other. Vertical angles are congruent, therefore, 2x + 50 = 7x. Solving for x you get 50 = 5x and x = 10. That means that that set of vertical angles each have a measure of 70. That's 140 so far. Around the "circle" created by those angles is a total degree measure of 360. So 360 - 140 = 220. Divide that in half to get the measure of angle BED and its vertical angle AEC. So your angle measure, BED is 110.
