First of all you should demand your teachers stop teaching you algebra in geometry class.
1
Linear pairs (and this is the geometry part) are angles that add to 180 degrees, supplementary angles formed by two lines crossing.
3n + 21 + 2n + 34 = 180
5n + 55 = 180
5n = 125
n = 25
mEFG = 3n + 21 = 96 degrees
mCFH = 2n + 34 = 84 degrees
These are indeed supplements, adding to 180 degrees.
2
ACD is a right angle because it makes a linear pair along DF with another right angle.
So
mACB + mBCD = 90 degrees
mBCD = 90 - mACB = 90 - 68
mBCD = 22 degrees
The correct answer is B, C and E
Experimental probability is the outcome during a certain experiment. add up the total number of times it was spinned. You should get 40. To find the experimental probability of each section, simply divide the number by 40. This will give you the percentage for each one. For example, spinner A. 14/40=.35 Multiply this by one hundred to find the percentage (35%). Do this for all and let me know if you need help converting them to fractions. :)

It's A) to find the slope.
The resulted equation is in slope-intercept form which gives the slope (-A/B).
Answer:
b=130
Step-by-step explanation:
b+(-43)=87
b+(-43+43)=87+43
b=130
