11a) False. If you simplify 8/30 you get 4/15 not 2/15.
11b) False. If you simplify 6/15, you get 2/5 not 3/5.
11c) true. 5/15 can be simplified to 1/3.
A:). because if you subtract on x+2y=14 from x+3y=18 you get y=4 and letter A is the only answer with positive 4 in the y coordinate (x,y)
Answer:
y=27
Step-by-step explanation:
Hmmm... a geometric sequence MUST have a fixed common ratio. If it is changing, then the sequence you are looking at might not be a geometric sequence at all. We'd need to see an example to be sure.
Combine like terms
Then you’ll get -7a-2b+8c-14 which is the answer.
