Answer: D
Step-by-step explanation:
<em> For example, if every piece of information was normally given in this question, we would first add -2 and z, then divide by -2 and arrive at -6. Now we have an unknown z, and we're going to do the reverse to find it.</em>
Step 1: Multiply -6 by -2. (12)
Step 2: Subtract 12 from -2. (14)
Result: Answer 14

Answer:
20. 44
21. 9
22. 94
23. 116
24. 17
25. 13
Step-by-step explanation:
Keep in mind complementary and supplementary angles. When two angles are right next to each other on a straight line, they add up to 180 degrees, such as the angles in 22 and 23. The other two angles are complementary angles since they add up to 90 degrees. So to solve for b, subtract the angle you are given from either 90 or 180 depending on if it is complementary or supplementary.
For question 20:
90 = b + 46
90 - 46 = b
b = 44
Then do the same for 21.
For question 22:
180 = b + 86
180 - 86 = b
b = 94
Then do the same for 23.
For the last two questions you need to remember that angles that are diagonal from each other are equivalent angles, so they equal each other.
For question 24:
70 = 4x+2
68 = 4x
x = 17
Do the same for 25.
83 = 6x+5
78 = 6x
x =13
Answer: Y=2/3x+4 that’s your rule/equation
A = (pi) * r^2
A = 3.14 * 8^2
A = 3.14 * 64
A = 200.96 rounds to 201.0 in^2
Circumference = 2
r
r = 12.5
2 *
* 12.5 ~ 78.540
The answer is about 78.540
