Answer:
Step-by-step explanation:
If we let x be the amount of live bait and y be the amount of natural bait, Then we can come up with the following inequalities;
We are told that John would like to get at least 3 pounds of live bait. At least 3 means 3 or more. Since x represents the amount of live bait, we have;
Moreover,we are informed that;
The store sells live bait for $12 a pound and natural bait for $7 a pound. x pounds of live bait would cost 12x while y pounds of natural bait would cost 7y. The total cost would thus be;
12x + 7y
but John only has a budget of $63. This implies that he can spend $63 at most, thus;
Finally we can have our last inequality as;
Answer:
$38.31
Step-by-step explanation:
Given:
Pure silver that cost $33.48 per ounce used to form $24.35 alloy/ounce.
Question asked:
How many ounces of pure silver were used to make an alloy of silver costing $27.87 per ounce?
Solution:
At cost $24.35/ounce, pure silver is mixed = $33.48
At cost $1/ounce, pure silver is mixed = 
At cost $27.87/ounce, pure silver is mixed = 
Thus, $38.31 ounces of pure silver were used to make an alloy of silver costing $27.87 per ounce.

Step-by-step explanation:
<em>x = 4</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>use </em><em><u>Thales theorem</u></em>
<em>x/(x + 8) = 4/12</em>
<em>12x = 4x + 32</em>
<em>12x - 4x = 32</em>
<em>8x = 32</em>
<em>x = 32 : 4</em>
<em>x = 4</em>
<em />
<em>4/(8 + 4) = 4/12</em>
<em>4/12 = 4/12 (true)</em>
<em />
<em>Good luck !</em>
