There are 124 dogs and cats in Miss Mulero's backyard. There are eight more dogs than cats. What is the total number of dogs in Miss Mulero's backyard?

There are 66 number of dogs in Miss Mulero's backyard.

Step-by-step explanation:

Let's set up equation for the given information.

Let there are 'd' number of dogs

and 'c' number of cats.

So, we can set up equation as

d+c=124

d=c+8

Let's solve the system of equations for 'd' and 'c'.

Substitute d as c+8 into the first equation then solve for 'c'

c+8+c=124

Combine like terms

2 c+8=124

Subtract both sides 8

2 c = 116

Divide both sides by 2.

c= 58

Plug in c as 58 into d=c+8

d=58+8

d=66

So, there are 66 number of dogs in Miss Mulero's backyard.

what's the question?

step-by-step explanation:

there is no question.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
