Answer:
The x-coordinate of the solution to this system of equations is <u>1</u>.
Step-by-step explanation:
Given,
We have to find out the x-coordinate of the equation.
Solution,
Let 
Again let 
Now using elimination method we will solve the equations.
For this we will add equation 1 and equation 2 and get;
Now on dividing both side by '9' we get;
Hence The x-coordinate of the solution to this system of equations is <u>1</u>.
Answer:
The best thing to do here is to put each of these into fractions, with the total (31) as the denominator.
14/31= silver
6/31= black
8/31= copper
3/31= various colours.
As you're looking for the keys that are silver or copper, you've got to add the two denominators together, which gives you 14+8= 22.
This cannot be simplified further, therefore, the probability of choosing either a silver or copper key is 22/31.
Hope this answer helps you :)
Have a great day
