Divide the new enrollment, 1260, by 1.05, which is 5% more than the enrollment last year.
1260 / 1.05 = 1200.
ANSWER:
C
**NOTE** Work backwards: 1200 * 1.05 (which is 5% more than 100%) = 1260. This suggests that trial
and error is a possible solution method to this problem, especially with a calculator.
Since AB is parallel to DE, angle ABC and angle CDE are equal, being alternate interior angles.
Likewise, angle BAC and CED are also equal.
Thus, angle BAC = 60°.
Because the 3 angles of a triangle sum to 180°, angle ACB = 80°.
Because angle ACB and angle BCE are a linear pair, their sum is 180°.
So, angle BCE = 100°.

Area of Triangle = ½ Base * Height
24 square units = ½ * 12 units * BD
24 = 6 * BD
BD = 4
ANSWER:
B
Because the triangle is isosceles, the 2 other sides are equal.
The other 2 sides are also equal to 8 * 2 + 3 = 19.
The perimeter is then 8 + 19 + 19 = 46.

To solve for x, first add 10 to both sides of the equation:
3x = 34
Then divide both sides of the equation by 3:
x = 34/3
Since that answer is not listed, 3 goes into 34 eleven times with a remainder of 1, or 11 and 1/3.
