Name a value for x that will complete the inequality that is shown. Then, explain why the value makes the inequality true.
Alex17521 [72]
<h3>Answer:    0.157</h3>

========================================================

Explanation:

Convert the fraction 9/50 to decimal form. You can use either long division or a calculator.

You should find that 9/50 = 0.18 which is the same as 0.180

So the original compound inequality is the same as saying 0.125 < x < 0.180

This tells us that x is between 0.125 and 0.180 where x is not equal to either endpoint. We simply need to pick anything in this interval. It can be anything you want (I recommend to use a number line to help pick a value). One such value is 0.157. There are infinitely many values you can select from.

The number 0.157 is between 0.125 and 0.180, ie  0.125 < 0.157 < 0.180

It's very similar to saying 157 is between 125 and 180, ie 125 < 157 < 180.

A law firm is going to designate associates and partners to a big new case. The daily rate charged to the client for each associ
lara [203]

Answer:

<u>The number of associates = 6  and the number of partners = 4</u>

Step-by-step explanation:

let the number of associates = x

let the number of partners  = y

The law firm assigned a total of 10 lawyers

∴ x + y = 10

∴ y = 10 - x ⇒ (1)

$8000 per day charged for these lawyers, The daily rate charged to the client for each associate is $600 and the daily rate for each partner is $1100.

∴ 600x + 1100 y = 8000 ⇒ (2)

By substitute from (1) at (2)

600 x + 1100 (10 - x) = 8000

solve for x

600 x + 11000 - 1100 x = 8000

-500 x = -3000

x = -3000/-500 = 6

At (1) to find y

y = 10 - 6 = 4

<u>So, the number of associates = 6  and the number of partners = 4</u>
