.At a certain animal shelter, the ratio of puppies to adult dogs is 7 to 4. This week there are a total of55 dogs in the shelter
Advocard [28]

Answer:

There are 35 adult dogs and 20 puppies

<em></em>

Step-by-step explanation:

<em>Represent the puppies with P and the Adult dogs with A</em>

Given

A : P = 7 : 4

Dogs = 55

Required

Determine A and P

First, we need to sum the ratios;

Total = A + P

Total = 7 + 4

Total = 11

Adult Dogs is then calculated as follows;

A = \frac{A\ Ratio}{Total} * Dogs

A = \frac{7}{11} * 55

A = \frac{385}{11}

A = 35

Puppies is calculated by subtracting the number of adult dogs from the total

P = Dogs - Adult\ Dogs

P = 55 - 35

P = 20

<em>Hence;</em>

<em>There are 35 adult dogs and 20 puppies</em>

-15.6 = -3.9r<br> please include an explanation of how you got your answer :) thanks
Mumz [18]

Here is the equation:

-15.6 = -3.9r

Since both decimals are negative, the answer will be positive.

  • Negative times Negative = Positive

Divide both sides by -3.9 to leave the variable alone:

-15.6 \div -3.9  = -3.9r \div -3.9 \\ 4 = r

r is equal to 4 → r = 4
