Answer: 16 + 35 + 24 + 14 = 89

Strategy #1 : You could break them up.

.... 10+30+20+10=70

.... 6+5+4+4=19

....70+19=89

Or, you can separate them into groups!

16+35=51

24+14=38

51+38=89

Hope this helps you out! If you need anymore help with math, let me know and I will be more than happy to help you out! ☺

Answer:

(16+35)+(24+14)

(16+14)+(35+24)

Step-by-step explanation:

This equation equals 89, basically what you would do is just add two numbers together and then add the sum of those two numbers, it makes the equation way easier to solve since you are not adding 4 numbers at a time, just 2.

.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

Step-by-step explanation:

Represent the puppies with P and the Adult dogs with A

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

$P = Dogs - Adult\ Dogs$

$P = 55 - 35$

$P = 20$

Hence;

There are 35 adult dogs and 20 puppies

Name the postulate or theorem, 50 points please help!

max2010maxim [7]

Hi!

When you use postulates and theorems, you need to make sure to only use the given information that you know. Look for the given statements, and congruence marks on the figure. Those are also considered given.

By looking, you are given an angle and a side. The side comes first. SU=TV.

So, that makes it so Side-Angle-Side would be the best option.

I hope this helps!
