4" x 2500 ft², namely 4 ft x 2500 ft², will just be 4*2500*ft*ft², or 10000 ft³.

since there are 27 ft³ in 1 yd³, then how many yd³ are there in 10000 ft³?
10000/27, that many yd³.
<h2>Steps:</h2>
So to solve for a variable, we must isolate it onto 1 side of the inequality. In this case, we must isolate r. Firstly, add 80 to both sides of the inequality:

Next, divide both sides by t:

Next, multiply both sides by -1. Since we are multiplying by a <em>negative</em> number, flip the inequality symbol as well:

<h2>Answer:</h2>
<u>In short, your final answer is
</u>
For this case we must do a conversion:
We have to by definition:
1 ounce equals 0.0625 pounds
Making a rule of three we have:
1 oz ------------> 0.0625 lb
67 oz ----------> x
Where "x" represents the number of equivalent pounds:

Thus, 67 ounces equals 4.1875 pounds
Answer:
67 ounces equals 4.1875 pounds
