An animal shelter houses dogs, cats, and rabbits. there are 126 animals at the shelter. of the animals, 1/3 are cats. three four
viva [34]
Given that an animal shelter houses three kinds of animals: dogs, cats and rabbits and it has a total of 126 animals. 1/3 of the animals are cats. This means, 1/3 of 126 is 42. So there are 42 cats. 3/4 of the remaining animals, which is 84 are dogs. So 3/4 of 84 is 63. So there are 63 dogs. 63 dogs plus 42 cats is 105 animals. 126 minus 105 is 21. Therefore, there are only 21 rabbits. Hope this helps.

Solve for x. Show each step of the solution. 5.5(8-x)+44=104-3.5(3x+24)
earnstyle [38]
5.5 ( 8 - x ) + 44 = 104 - 3.5 ( 3x + 24 )

Distribute 5.5 through the parenthesis.

44 - 5.5x + 44 = 104 - 10.5x - 84

Add the numbers.

88 - 5.5x = 20 - 10.5x

Move variable to the left side and change its sign.

88 - 5.5x + 10.5x = 20
-5.5x + 10.5x = 20 -88

Collect like terms.

5x = 20 - 88

Calculate the sum or difference. 

5x = - 68

Divide both sides by 5.

x = - 68 / 5

Alla [95]

Answer:

h=\frac{1}{6}

Step-by-step explanation:

Given:

A=\frac{1}{2h} (B+b)\\

A=21, B=2, b=5 ,h= ?

We have to find the value of  'h'

So, putting the given values in the equation to find the value of 'h'.

          A=\frac{1}{2h} (B+b)

Implementing the given values in the given equations:

         

                              21=\frac{1}{2h}(2+5)\\\\ 21=\frac{1}{2h} (7)\\\\\frac{1}{2h}=\frac{21}{7}\\\\  \frac{1}{2h}=3 \\\\h=\frac{1}{6}

So, the value of 'h' is

                       h=\frac{1}{6}
