The first one, 18cm, 6cm, 13cm. First, we need to learn about the triangle equality, it is A + B > C.

So if we take 6+18 it would be 24 which is greater than 13.

Also we have to try 6+13 it would be 19, which is greater than 18.

Then we also have to try 18+13, which is 31. And it is greater than 6.

When it does not fail the triangle equality, it can be a triangle.

Answer:

Step-by-step explanation:

You need to create two equations for each company and then set them equal to each other. The keywords base fee means you will pay this amount regardless, so this amount stays constant and it will be the constant in the equation. The other keyword is per. Per will link the variable with the coefficient.

The first equation for company M:

y = 12x + 60

The second equation for company N:

y = 9x + 120

Set the equations equal to each other.

9x + 120 = 12x + 60

Solve for x. I am going to subtract 9x from both sides first.

9x - 9x + 120 = 12x -9x +60

120 = 3x +60

Now, I will subtract 60 from both sides.

120 - 60 = 3x + 60 - 60

60 = 3x

Finally, I will divide both sides by 3

60/3 = 3x/3

x = 20

20 is how many guests it will take for the total cost to be the same.
