Answer:
for the first one its a=8
for the second one the answer is their is no solution
for the last one the answer is p = -1.
Step-by-step explanation for the last one:
1)Expand.
30-6p=16-20p
2) Subtract 16 from both sides.
30-6p-16=-20p
3 Simplify 30-6p-16 to -6p+14.
-6p+14=-20p
4 Add 6p to both sides.
14=-20p+6p
5 Simplify -20p + 6p to −14p.
14=-14p14=−14p
6 Divide both sides by−14.
-1=p
7 Switch sides.
p=-1
Both the mean and median
Median 80+88= 168/2= 84%
Mean 504/6= 84%
73%,
76%,

Answer:
12
Step-by-step explanation:
divide the total by 4, when you get your answer, divide that by 6, what is you remainder?
Step-by-step explanation:
By Exterior Angle Theorem,
81° + b = 117°.
=> b = 117° - 81° = 36°.
