1. **Problem statement:** Given the line equation $3x - 2y = 10$, find:

1. **Stating the problem:** We have two quantities whose sum is $y$. One varies directly as $x^2$ and the other varies inversely as $x$. Given $y=32$ when $x=2$ and $y=86$ when $x=

1. **State the problem:** Solve the inequality $5x + 3 > 2x - 7$. 2. **Isolate the variable terms:** Subtract $2x$ from both sides to get all $x$ terms on one side.

1. **Problem:** Find the roots of the quadratic equation $$5 - 5x - 2x^2 = 0$$. 2. **Rewrite the equation in standard form:**

1. **State the problem:** We have three pipes filling a tank with different rates and a leak draining the tank. We want to find the total time to fill the tank completely.

1. The problem states that the answer is \(\frac{25}{512}\).\n2. This fraction is already in simplest form because 25 and 512 have no common factors other than 1.\n3. 25 is \(5^2\)

1. **State the problem:** We have a broken clock where the minute hand completes one full revolution in 72 minutes instead of the usual 60 minutes, and the hour hand moves normally
