Erich K.

Since "porta, portae" is a first declension noun, we must follow the first declension now endings. The answer should be: porta, portae, portae, portam, porta, portae, portarum, portis, portas, portis.

Question:

Using PEMDAS, solve the following equation: (3 + 7)/2 + 10 * 3 = ?

Erich K.

First, we add what's in the parentheses which is 10. Divide the 10 by 2, the next step in PEMDAS. Now, we have 5. Now, before we can add the 10 to the 5, we must multiply the 10 by 3. 10 * 3 = 30 Now, we can add the 30 and the 5 to give us: 35

Question:

2x - 7 = 3x + 5

Erich K.

First, add seven to both sides. The equation should look like: 2x = 3x + 12 Next, subtract the 3x from both sides. The equation should look like: -x = 12 Finally, divide both sides by -1. The equation (and the final answer) should be: x = -12
