A pet home owner wants to keep the ratio of cats to dogs at 3:5. She has 21 cats, how many dogs are there in the pet home?

klemol [59]

Answer:

There are 35 dogs in the pet home.

Step-by-step explanation:

3:5 is the ratio, 3 being cats and 5 being dogs

Since there are 21 cats, you would do 21/3 to find the ratio value - which is 7

Now, multiply 5 times 7 to get the amount of dogs, which is 35.

Does anyone know where the a in front of the parentheses for the LCD : a(a+5)(a-6) came from?

lukranit [14]

Answer:

See below

Step-by-step explanation:

If you factor $a^2-a-30$ you get $\left(a^2+5a\right)+\left(-6a-30\right)$

= $a(a+5)-6(a+5)$

= $a(a+5)(a-6)$

That's where the a comes in
