To solve for U, we can start by isolating U on one side of the equation.
Given: T = 3U/E
To isolate U, let's first multiply both sides of the equation by E:
ET = 3U
Next, divide both sides by 3:
ET/3 = U
Therefore, U = ET/3.
Given: T = 3U/E
To isolate U, let's first multiply both sides of the equation by E:
ET = 3U
Next, divide both sides by 3:
ET/3 = U
Therefore, U = ET/3.

To solve for r, we can start by combining like terms on both sides of the equation.
Given: 0.25r - 0.125 + 0.5r = 0.5 + r
First, let's combine the r terms on the left side:
0.25r + 0.5r - r = 0.5 + 0.125
Simplifying the left side:
0.75r - r = 0.625
Now, let's combine the r terms:
0.75r - r = 0.625
0.75r - r is equivalent to (0.75 - 1)r, which simplifies to -0.25r:
-0.25r = 0.625
To solve for r, we can now divide both sides by -0.25:
(-0.25r) / -0.25 = 0.625 / -0.25
Simplifying:
r = -2.5
Therefore, r = -2.5.
Given: 0.25r - 0.125 + 0.5r = 0.5 + r
First, let's combine the r terms on the left side:
0.25r + 0.5r - r = 0.5 + 0.125
Simplifying the left side:
0.75r - r = 0.625
Now, let's combine the r terms:
0.75r - r = 0.625
0.75r - r is equivalent to (0.75 - 1)r, which simplifies to -0.25r:
-0.25r = 0.625
To solve for r, we can now divide both sides by -0.25:
(-0.25r) / -0.25 = 0.625 / -0.25
Simplifying:
r = -2.5
Therefore, r = -2.5.

Let's denote the width of the pool as w.
The formula for the perimeter of a rectangle is P = 2(l + w), where l is the length and w is the width.
Given that the length of the pool is 22 feet, we can substitute these values into the perimeter formula:
P = 2(22 + w)
According to the problem, the perimeter of the pool must be no more than 120 feet. Therefore, we can set up the following inequality:
2(22 + w) ≤ 120
Next, we can simplify the inequality:
44 + 2w ≤ 120
Subtracting 44 from both sides of the inequality:
2w ≤ 120 - 44
2w ≤ 76
Finally, dividing both sides of the inequality by 2:
w ≤ 76/2
w ≤ 38
Therefore, the width of the pool must be less than or equal to 38 feet in order to satisfy the given conditions.
