Answer:

Step-by-step explanation:

You are using the wrong accounting system

Forget the nine dollars.

If the thing bought was 25 dollars, then each one of A B and C put in 25/3 = 8.3333 dollars. If 1 dollar each was going back, then the sum became 9 1/3 dollars. 3 * 9 1/3 = 27 + 1 = 28. There is 2 dollars left. Everything is fine.

25 + 3 = 28

The three each got 1 dollar back. But the total accounted for is 25 + 3 = 28

There's 2 left over. That makes 30. Everything's fine. There is no missing dollar.

I need help for my friend!
givi [52]

Answer:

16

Step-by-step explanation:

Let the number be X

3/4 of X = 15

Multiplying out gives;

3X = 4x15

3X= 60

X = 20

Therefore, 4/5 of 20

Putting X = 20 we have;

4/5 x 20 = 16.

-------------------------------------------------

16-3/4= 15.25

Write equivalent expressions of 18m+42n​
serious [3.7K]

Answer:

See explanation

Step-by-step explanation:

Given:

18m + 42n

These two variables are not the same, so we can't add the two terms. However, we can factor out a number out of this expression.

The GCF of 18 and 42 is 6.

We can draw 6 out of this expression to get 6(3m + 7n).

This is an equivalent expression.

We can also draw 2 out to get 2(9m + 21n).

We can also draw 3 out to get 3(6m + 14n).

We can also draw 1/2 out to get (1/2)(36m + 84n).

There are endless possibilities, but these are a few. You get the idea!

Please mark as Brainliest! :)
