You said: "According to the problem, there are 6 wings and no other animal has wings. So since chickens have 2 wings, there are THREE chickens.

Since chickens have 2 eyes and 2 legs, we can do 3 * 2 = Subtract 6 from 50 legs and 48 eyes

So we have 44 legs and 42 eyes.

Cats have 4 legs, so there must be 44/4 = 11 cats (fish have no legs)

11 cats * 2 = 22 eyes.

So 42-22 = 20 eyes left.

20 eyes, and fish have two eyes, so 22/10 = 2 fish.

The number of pets is 6 chickens + 11 cats + 2 fish = 19 animals. (do you see the error?)

The answer should be 24"

The right answer: There are 48 eyes, and that means there are 24 pets in total...

each animal has two eyes! 48/2=24!

What you got wrong: it is highlighted above. For the Fish, you said there are 20 eyes left and fish have two eyes, that is right, but later, you did 22/10 instead of 20/2. there are 10 fish. For the final answer, you said The number of pets is 6 chickens + 11 cats + 2 fish = 19 animals​, but I believe you also said that there are 3 chickens---not 6. LOL. The right answer is: The number of pets is 3 chickens+11cats+10fish=24 animals. (you understand now?)

soultion1: Every 30 seconds 3-2=1 toys are put in the box, so after 27\cdot30 seconds, there will be 27 toys in the box. Mia's mom will then put 3 toys into the box and we have our total amount of time to be 27\cdot30+30=840 seconds, which equals 14 minutes

soultion2: Though Mia's mom places 3 toys every 30 seconds, Mia takes out 2 toys right after. Therefore, after 30 seconds, the two have collectively placed 1 toy into the box. Therefore by 13.5 minutes, the two would have placed 27 toys into the box. Therefore, at 14 minutes, the two would have placed 30 toys into the box. Though Mia may take 2 toys out right after, the number of toys in the box first reaches 30 by 14 minutes

√ [ (3 - 0)^2 + (3 - 0)^2 ] = √  [9 + 9 ]  = √18  =  3√2 units

2 and 3.

The numbers are 31, 58, 98, x, and x.
The mode, M, is x since it's repeated twice.
The mean, A, is 

a= (31+58+98+2x)/5

(187+2x)/5=3/2x

(187+2x)=15/2x

2(187+2x)=15x

374+4x=15x

11x=374

x=34



 

Proof, please.

nice

good work guest. I was about to give the answer. 

another hint: If you are only given one endpoint and a midpoint, you know what the middle of the line segment is. Since the midpoint is half of what the line segment's length is, all you have to do is find the distance between the endpoint given and the midpoint, then add that coordinate to your midpoint and get your other endpoint.
