1. x=3.03
2.x=0.5
3.x=4/3
4.x=2
5.x=10
It could be either y = 12.75x or y = 13x. Check if you made a typing error because these rates are both better than B
Answer:
1200
Explanation:
Order does not matter, if we said xyz order, it would still not make a difference if it was zyx or yzx hence we use the combination formula:
nCr = n! / r! * (n - r)!
where n= total number of items
r= number of items chosen at a time
Combinations are used when the order of events do not matter in calculating the outcome.
We calculate using the formula:
(30×20×12)÷3!=1200
There are therefore 1200 ways for the three distinct items to not be in same row or column
The solution of given equation is x=2
Further explanation:
In order to solve the given equation we have to isolate the variable x on one side of the equation. The process will involve distributive property and simplification.
Given:
