Answer:
Use 49 ounces of the 14% allow and 41 ounces of the 23% alloy.
Step-by-step explanation:
Each ounce of the 14% copper contains 0.14 ounce of pure copper.
Each ounce of the 23% copper contains 0.23 ounce of pure copper.
Each ounce of the 18.1% copper contains 0.181 ounce of pure copper.
Use x ounces of the 14% and y ounces of the 23% to make 90 ounces of 18.1% alloy.
x+y  = 90
y = 90-x
0.14x + 0.23y = 0.181·90
0.14x + 0.23(90-x) = 16.29
0.14x + 20.7 - 0.23x = 16.29
-0.09x + 20.7 = 16.29
4.41 = 0.09x
x = 49
y = 90-x = 41
Use 49 ounces of the 14% allow and 41 ounces of the 23% alloy.
 
        
             
        
        
        
The absolute expression |x - y| is rewritten in the form of without using absolute value notation will be x - y.
<h3>What is an absolute function?</h3>
The absolute function is also known as the mode function. The value of the absolute function is always positive.
The absolute function is given as
f(x) = | x |
If the value inside the mode operator is greater than zero, then simply the mode operator is eliminated. 
The notation of the absolute function is given below.
|x - y| If x>y
Then the absolute function is given as,
|x - y| = x - y
The absolute expression |x - y| is rewritten in the form of without using absolute value notation will be x - y.

Answer:
hope this helps
Step-by-step explanation:
x > −5
 
        
                    
             
        
        
        
<u>1</u> : 3
8
Make the whole number a fraction, by putting it over 1.
<u>1</u> : <u>3</u>
8   1
Turn the second fraction upside down and multiply: 
<u>1</u> . <u>1</u> =  <u>1 </u>
8   3     24
S = 1/24
