Answer:
The average population growth per year is 102.
Step-by-step explanation:
From the given data, we can find the slope which will give us the average rate of change. Our points are:

angle A = 30
(2x-9) = (2x+21)
+9 +9
2x=2x+30
-2x -2x
=30
Let x be the total number of questions. We know that Jess answered correctly 35 of them, and those 35 are the 74.47% of all questions.
So, can build the proportion linking the correct answers to the total number of questions:
Solving for x, we have

Answer: x = 5</h3>
============================================================
Explanation:
The square marker indicates a 90 degree, or right angle.
The two smaller angles (3x and 75) both combine to the larger 90 degree angle. That's what it means when they say we have complementary angles.
Add up the smaller angles, set the sum equal to 90, and solve for x.
3x+75 = 90
3x+75-75 = 90-75 ....... subtracting 75 from both sides
3x = 15
3x/3 = 15/3 ..... divide both sides by 3
x = 5
---------------
If x = 5, then 3x = 3*5 = 15
Then we can see that 15+75 = 90 to help check our answer.
