### Subject: Pre-Algebra

Solve the following problem when a=3, b= 2 and c=4 a + c - b

If you substitute the numbers for the variables in the problem, you would have the expression 3 + 4 - 2. According to the order of operations, you have to do 3+4 first, which is 7. What is left to solve is 7 - 2, which gives you an answer of 5.

### Subject: Biology

What are the steps of mitosis, list them and describe what happens in each step.

Prophase: the spindle fibers begin stretching. Metaphase: the chromosomes are lined up along the metaphase plate, and the centrosomes are at either end of the cell. Anaphase: the chromosomes all split at the centromere, and begin moving toward the opposite sides of the metaphase plate. Telophase: the nucleus and cytoplasm begin dividing to create 2 diploid cells.

### Subject: Algebra

Solve for x when 9x+5 = 50

To solve this, you would first have to subtract 5 from both sides, leaving you with the equation 9x = 45. Next, you divide by 9 on both sides, giving you x = 5.
