Draw a model... write an equation and solve....this is the directions for a  4th grade math homework problem....Help?????
At the dog show, there are 4 times as many boxers as spaniels. If there are a total of 30 dogs, how many dogs are spaniels??

Sagot :

Iloveonedirectionidn
Boxers = b
Spaniels = s

[tex]b=s*4[/tex]
[tex]s+b=30[/tex]

Now you have two equations - one that tells you the number of boxers in relation to spaniels and one telling you the number of each breed in relation to the total number of dogs. Solve using substitution.

[tex]s+(4*s)=30 \\ 4s+s=30 \\ 5s=30 \\ s=6[/tex]

There are 6 spaniels.
