So in plain English it's saying if A Is an element of B, then A and B equals A or B. This is true sometimes
16x = 2250 + 6x
x = 225
So he must sell 225 cameras
16(275) = 4400
6(275) = 1650
4400 - (1650 + 2250) = 500
$500 profit
Answer:
24
Step-by-step explanation:
Plug in numbers for letters...
4(12) - (8)(3)
48 - 24
24
Since LM = AM, point M must be on the perpendicular bisector of AL. Since AM = BM, BL must be perpendicular to AL. This makes ∆ALC a right triangle with hypotenuse AC twice the length of side AL. Hence ∠LAC = ∠LAB = 60°, and AL is angle bisector, median, and altitude.
ΔABC is isosceles with ∠A = 120°, and ∠B = ∠C = 30°.
