Answer:
20
Step-by-step explanation:
5 divided by 1/4= 20
Simplifying
120 + -28a = 78
Solving
120 + -28a = 78
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-120' to each side of the equation.
120 + -120 + -28a = 78 + -120
Combine like terms: 120 + -120 = 0
0 + -28a = 78 + -120
-28a = 78 + -120
Combine like terms: 78 + -120 = -42
-28a = -42
Divide each side by '-28'.
a = 1.5
Simplifying
a = 1.5

Answer:
I believe C.
Explanation:
I am pretty sure it's C but I don't really see it too well so I can't read the top two the best.
Answer:
27
Step-by-step explanation:
The rule will be
Ni=(i-1)*5+2
- i=1 → N=(1–1)*5+2=0*5+2=0+2=2
- i=2 → N=(2–1)*5+2=1*5+2=5+2=7
- i=3 → N=(3–1)*5+2=2*5+2=10+2=12
- i=4 → N=(4–1)*5+2=3*5+2=15+2=17
- i=5 → N=(5–1)*5+2=4*5+2=20+2=22
- i=6 → N=(6–1)*5+2=5*5+2=25+2=27
