Back

Sale Price = $100 - ($100 * 0.30) = $70

Front

How do you calculate the final price after applying an additional discount to a sale price?

Back

What is the slope of a line given in the standard form Ax + By = C?

Back

The slope (m) can be found using the formula m = -A/B.

Front

For the line 9x + 4y = 7, what is the slope?

Back

How do you find the measure of an angle in a triangle if you know the other two angles?

Back

The measure of the third angle can be found using the formula: Third Angle = 180° - (Angle 1 + Angle 2).

Front

If ∠ACD = 65°, what is the measure of the other angles in a triangle if the other two angles are equal?

Back

Let the other angles be x. Then, 65 + x + x = 180, so 2x = 115, thus x = 57.5°.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180°.
