Answer:
<h2>36.14 pounds of 34% copper alloy and 9.86 pounds of 48% copper alloy</h2>
Step-by-step explanation:
First alloy contains 34% copper and the second alloy contains 48% alloy.
We wish to make 46 pounds of a third alloy containing 37% copper.
Let the weight of first alloy used be 
in pounds and the weight of second alloy used be 
in pounds.
Total weight = 
Total weight of copper = 
Subtracting 34 times first equation from second equation,
∴ 36.14 pounds of first alloy and 9.86 pounds of second alloy were used.

Step-by-step explanation:
- The equivalent inequality for the number line is x < 8
- The equivalent inequality for the number line is x ≥-5
<h3>Inequality functions </h3>
The inequality expression is an expression not separated by an equal sign,
11) The equivalent inequality for the number line is x < 8. This shows that the values of x that make it true must be less than 8.
Note that the sign is less than because the circle is open and moves towards the left of the number line
11) The equivalent inequality for the number line is x ≥-5. This shows that the values of x that make it true must be greater than or equal to 8.
Note that the sign is greater than or equal to because the circle is closed and moves towards the right of the number line
