Answer:
r=2
Step-by-step explanation:
r + 8 r + 11 = 29
( 1 + 8 ) r + 11 = 29 9 r + 11 = 29
Now we can isolate and solve for r while always keeping the equation balanced: First, subtract 11 from each side of the equation:
9 r + 11 − 11 = 29 − 11
9 r + 0 = 18
9 r = 18
Now we can divide each side of the equation by 9 to get
r : 9 over 9 = 18 under 9
1 r = 2
r = 2

Answer:
the bike was bought for $20
Step-by-step explanation:
this is true because 20*2.50 is 50
2.50 is the same as 250%
Answer:
If the sum of first 6 terms is 9 times to the sum of first 3 terms of the same G.P., then common ratio of the series will be. Solution: Let a be the first term and r be the common ratio of the GP. Hence option (2) is the answer.
