Y would equal -28 when X equals 20.

Since they vary directly, all you do is divide 20 by -5 to find the variation between X and Y. You will get -4 which you multiply to 7, to get you final answer. Thus making Y equal to -28.

I hope this helps!

The math problem is 100 x 0.496
Setler79 [48]

Answer:

What is the value of x? Thanks for the help
-BARSIC- [3]
Hello! I can help you! First things first, because they are both the same angles on opposite sides, let's set this up in the form of an equation and solve for "x". It would be set up like this:

2x + 20 = 3x - 30

You see up top that it says 2(x + 10). What you would do is multiply what's in the parenthesis by 2, in order to get 2x + 20. Then put the equal sign and write 3x - 30. Subtract 3x from both sides to get -1x + 20 = -30. Subtract 20 from both sides to get -1x = -50. Divide each side by -1 to isolate the "x". In this case, because you are dividing a negative number by a negative number, your quotient will be positive. -50/-1 is 50. Let's plug in the value as "x" and see if it works. 50 * 2 is 100. 100 + 20 is 120. 50 * 3 is 150. 150 - 30 is 120. 120 = 120. There. x = 50.
