Answer:
8 rabbits
22 chickens
Step-by-step explanation:
c = chickens
r = rabbits
heads - c + r = 30
legs - 2c + 4r = 76
We can now use these two equations to create one by isolating the variable (c) in the first equation.
c = 30 - r
2c + 4r = 76
2(30 - r) + 4r = 76
60 - 2r + 4r = 76
2r = 16
r = 8
Now we know that there are 8 rabbits, which means that there has to be 22 chickens in order to have 30 heads.
9m +18= -6m -42
9m +6m= -42-18
15m = -60
m= -4
The answer would be 8 cubed, or 512 feet. just multiply the side by the width by the height and you have your answer.
Uhh didnt I just answer this? It is 3/13
Answer:
-36
Step-by-step explanation:
They gave you the numerical value of h. Think of h as just a placeholder. So each time you see h, you replace it with its numerical value. This is true for all letters such as the famous x and y.
<u>Replace h with -6</u>
2(-6) + 4(-6) = -36
