dean ate 8 cookies
elise ate 4 cookies
clark ate 6 cookies
Step-by-step explanation:
i am pretty sure this is correct
make a diagram of a circle with twelve spots
change 1/3 to 4/12, so color in 4 spots for dean
multiplie 1/4 times 8/12 ( the remaining spots), color in that number of spots for elise
do the same with 1/2, color in the amount of spots for clark
you will have 3 spots left, meaning each spot is worth 2 cookies

Answer:
- airplane: 225 mph
- wind: 45 mph
Step-by-step explanation:
The average speed with the wind is (540 mi)/(2 h) = 270 mi/h.
The average speed against the wind is (540 mi)/(3 h) = 180 mi/h.
Let a and w represent the speeds of the airplane and wind, respectively.
a + w = 270 . . . . speed with the wind
a - w = 180 . . . . speed against the wind
2a = 450 . . . . . . sum of the two equations
a = 225 . . . . . . divide by 2
w = a -180 = 45
The speed of the airplane is 225 miles per hour; the speed of the wind is 45 miles per hour.
