Indicate your specific subject in the "School Subject" box, so those with expertise in the area will respond to the question. Also, it would help if you proofread your questions before you posted them. How many of each color? How specifically do you want it rounded?

algebra
Add the two equations to cancel out y. 5x = -15 You should be able to work it from there.

Statistics
What is the standard deviation? T = 50 + 10SD

Algebra

Scientific nottion
Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown. Online "^" is used to indicate and exponent, e.g., x^2 = x squared. 3.0 * 10^6

From your data, it looks like 84 took politics and 16 took history. There is no information to indicate how many took both.

We cannot graph here. Put various values for x and solve for y. Put these on a scatterplot to graph. I'll start you out. if x = 0, 4y > 20, y > 5.
