Answer: The probability is 6/15 or 40%
Step-by-step explanation: In your question, you said Isabelle's book collection has 15 books and in that collect she has 6 autobiographies. So they probability as a fraction is 6/15.
65% is bigger than 0.56 which would be 56%
I guess there's something missing from the question
Answer:
34 sold for $20
55 sold for $35
Step-by-step explanation:
20x+35y=2605
y=(98-x)
20x+35(89-x)=2605
Solve for x
20x+3115-35x=2605
20x-35x=2605-3115
-15x=-510
x=34
Answer:
- 6
Step-by-step explanation:
First you have to cross multiply, then ypu will get,
11(2x+3)=3(3x-15)
22x+33=9x-45
22x-9x= - 45-33 (by using transposing method)
13x= - 78
X= - 78/13
Then bring it to its lowest form, you'll get,
X= - 6
