Why can you use cross products to solve the proportion 18/5 = x/100 for x ?
Tcecarenko [31]

Answer:

Yes, you can use cross products to solve for x in this proportion. Also, x is 360.

Step-by-step explanation:

Yes, you can use cross products to solve for x in that proportion.

Here's how you do it :

\frac{18}{5} = \frac{x}{100}

We cross product, getting :

18 * 100 = 5 * x

1800 = 5x

Divide by 5 on both sides to get x by itself.

360 = x

Yes, you can use cross products to solve for x in this proportion. Also, x is 360.

What is the slope? ​
Luda [366]

Answer:

-3

Step-by-step explanation:

Find two easy to read points on the graph.

I see (0, 1) and (-1, 4).

slope = rise/run

Start at (0, 1). Go up 3 units. That is a rise of 3. Now go left 1 unit. That is a run of -1.

slope = rise/run = 3/(-1) = -3

Susan is attending a talk at her sons school. There are 8 rows of 10 chairs where 54 parents are sitting. Susan noticed that eve
kherson [118]

Answer:  4

<u>Step-by-step explanation:</u>

To fit the maximum amount of people in one row, you would have 3 couples and 1 single = 7 parents.

If we continue the maximum amount of people for 7 rows, we get 49 parents seated.

Since a total of 54 parents are seated, that leaves 54 - 49 = 5 parents remaining to be seated in the last row.  These parents can be seated as 2 couples and 1 single. If you put the single at the end of the row, there will be 4 seats between the couple and the single.
