Step-by-step explanation:
50,50,54,56,60,62,63,64,79,72,72,
median ids the number at the center
50,50,54,56,60(62)63,64,79,72,72
x = , y =
1. Isolate for x in one of the equations:
2x = 9x - 14y
2x-9x = 9x-9x -14y
-7x = -14y
-7x/-7 = -14y/-7
x = 2y
2. Substitute 2y in for x in the second equation:
9(2y) = 40 - 14y
3. Simplify:
18y = 40 - 14y
4. Isolate for y:
18y+14y = 40 -14y+14y
32y = 40
32y/32 = 40/32
y =
5. Substitute the new y-value into the simplified expression x = 2y:
x = 2(5/4)
x =

2 times 2^30 simple means that = (2^1) x (2^30)<span>In multiplying numbers of the same base (in this case 2), the exponents are just added, therefore giving us:</span>
(2^1) x (2^30) = (2^31)
<span>2 to the 31 power</span>
the answer is c. 35% increase daily
