Answer:
Step-by-step explanation: You need to find a the lowest number that the denominators can be timed by. In you're case. You can just times 5 by 2 = 10
So that both the denominators are 10. And the denominator that was once 5. The numerator of that fraction also needs to be timed by 2.
So then you have 7 18/10 - 6 15/10
Then you can convert them to to proper fractions 8 8/10 - 7 5/10
Then you can take away the fractions so it's
8 8/10 - 7 5/10 = 1 3/10
Answer:
n+524
Step-by-step explanation:
you add both years worth of biking together!
The logarithm of a quotient can be written as a difference of logarithms:
You can also think of this as a combination of the product-to-sum and reciprocal/power properties of logarithms:
To summarize,
Answer:
1.A
2.C
if your know the theory, it's like that and the third is prove that works for n+1
