they are both finite because 2/10=0.2, and 0.2 doesn't go on forever. -120/6=-20, which also has an end, and doesn't go on forever. I hope this helps :)

Can you help me with this!!!!!!!!!

a. The first variable is x and the second variable is y.

b. The equations are $x+y=12$ and $x-y=8.$

Step-by-step explanation:

Step 1:

The first step is to define the variables. The variables can be any two symbols, letters, characters, etc.

Here let the first variable be x and the let the second variable be y.

So the variables are defined as x and y.

Step 2:

The sum of the given variables is 12.

The first variable + the second variable = 12,

$x+y=12.$

The difference between the two variables is 4.

The first variable - the second variable = 4.

$x-y=4.$

Step 3:

If we add both the equations we get, $2x =16, x= 8$ and $y=4.$

x = 8 and y = 4.

Berta is planning a party for her friends. The room rental cost is $50 plus an additional $3 per person to cover food costs. Ber

Answer:

A. 3x+50 ≤ 100; 16 people

Step-by-step explanation:

If x represents the number of people at Berta's party, then the cost of food is 3x. Added to the $50 cost of room rental, the total charge Berta must pay will be ...

3x +50

She wants this to be at most $100, so her inequality is ...

3x +50 ≤ 100

Berta can solve this by subtracting 50, then dividing by 3.

3x ≤ 50

x ≤ 16 2/3

Since x represents a number of <em>people</em>, and it is not possible (or desirable) to have 2/3 of a person show up, the maximum number of people that can attend Berta's party is 16.
