Answer:
x=10 and y=15
Step-by-step explanation:
1: Plug y into the equation
y=2x-5
5x-4(2x-5)=-10
2: Solve for x
-3x=-30
<em><u>x=10</u></em>
3: Plug x into the other equation
x=10
y=2(10)-5
4: Solve for y
<u><em>y=15</em></u>

So first off, the answer to this is 24 now think of x as the real or original sum or amount, also y as the new sum or amount.
y * 1.5 is x, and y+12 is x. Now flip that to figure out what is y, also which is what we need, and you have x/1.5 = y as well as x-12 = y. Use the equal values method and make an equation x/1.5=x-12. solve this equation to get x, which is 36. to figure out the new amount, y, you need to minus 12, which can help you get the answer which is 24.

Answer:
x = 30°
Step-by-step explanation:
x° is the other acute angle of the right triangle with 60° as the acute angle at the center of the circle. (The tangent line makes a right angle with the radius at the point of tangency.)
