Answer:

2

Step-by-step explanation:

In algebra, you can replace the letters in an equation with whatever number they equal.

So because a = 2, we can replace the a in this formula with the number 2

We can do the same thing for the rest of these letters!

so...

a + b + c

becomes

2 + 1 + (-1)

now all we need to do is solve :)

2 + 1 + (-1)

3 + (-1)

3 - 1

Mr. Smith and Mr. Kelly are business partners they agreed to divide the profits in the ratio of 3 to 2 the profit amount of 24,0
nikitadnepr [17]

Answer: Mr. Smith makes 14,400, Mr. Kelly makes 9,600

Step-by-step explanation: First add the ratio together. 3+2=5.

Then divide 24,000 into five parts, 24,000/5 = 4,800.

After getting 4,800, multiply 4,800 by 3 to get Mr. Smith's portion of the money received. 4,800 x 3 = 14,000.

And you can do the same for Mr. Kelly but use 2 instead of a 3.

4,800 x 2 = 9,600

To check your work you can add the two answers together

9,600 + 14,400 = 24,000.
