1. Simplify the following expression: 
2x + 4y - 3x - 2y 
Solution: 
2x - 3x + 4y - 2y = -x + 2y 
2. If a recipe calls for 2 1/2 cups of flour, and you want to make 1/2 of the recipe, how much 
flour do you need? 
Solution: 
To make 1/2 of the recipe, you need half the amount of flour, which is: 
(1/2) x 2 1/2 cups = 1 1/4 cups 
3. Solve for x: 
2(x + 5) = 12 
Solution: 
First, distribute the 2: 
2x + 10 = 12 
Then, subtract ...

Joo-won is writing code to calculate the volume of a cone based on this formula: 
 
Volume=(Pi(r)^2)(h/3) 
 
He's testing his code on this cone: 
The code starts with these variables, where radius represents rrr and height represents hhh: 
radius ← 2 
height ← 5 
The built-in constant PI stores an approximation of PI 
Which expression correctly calculates the volume? Ans- PI * (radius * radius) * (height /...
