Step-by-step explanation:
When factoring you'd take out the greatest common factor, that being ten for this problem. The greatest common factor would go on the outside of your parenthesis. What remains after dividing the greatest common factor would go on the inside of the parenthesis.

Step-by-step explanation:
120-60=60 which is how much he gets back from selling a bike. divide 2700/60=45 bicycles that have to be sold.
QUESTION:
The code for a lock consists of 5 digits (0-9). The last number cannot be 0 or 1. How many different codes are possible.
ANSWER:
Since in this particular scenario, the order of the numbers matter, we can use the Permutation Formula:–
- P(n,r) = n!/(n−r)! where n is the number of numbers in the set and r is the subset.
Since there are 10 digits to choose from, we can assume that n = 10.
Similarly, since there are 5 numbers that need to be chosen out of the ten, we can assume that r = 5.
Now, plug these values into the formula and solve:
= 10!(10−5)!
= 10!5!
= 10⋅9⋅8⋅7⋅6
= 30240.
we have it has...
5n-2/8=n+8/3
you have to cross multiply..giving us
3(5n-2)=8(n+8)
15n-6=8n+64
collect like terms
15n-8n=64+6
7n=70
n=10
I really hope that helps..bye
