The answer is the top one.
U is 2
You collect like terms meaning you do 17-8= 9u
9u=18 divide both sides by 9 and get U=9
Answer:
39.6
Step-by-step explanation:
i would give explanation but im bad at doing that
1. A geometric sequence has a common ratio. You can find the ratio by dividing every number by its previous one. If it is consistent, then the series is geometric.
a: 8/1=8, 27/8=3.375
b: (-3/2)/3=-1/2, (3/4)/(-3/2)=-1/2
c. 7/4=1.75, 10/7=1.429
d. 20/25=0.8, 14/20=0.7
Choice b is the only one that has a common ratio, so it is a geometric series.
2. Every term is multiplied by 1/3, so the common ratio is 1/3. d is the answer.
Answer:
b = -1
Step-by-step explanation:
-7+b= -8
Add 7 to each side
-7+7+b= -8+7
b = -1
