Answer:
There are total number of pet fish and reptile pets are
.
Step-by-step explanation:
Number of pet fish are
and the number of pet reptiles are
.
It is required to find the total number of pet fish and reptile pets in the United States. It can be done by simply adding the above numbers such that total numbers are given by :

So, there are total number of pet fish and reptile pets are
.
The three scores are 86, 74, and an unknown score x. The average (i.e. the sum divided by how many there are) is 80, so we have

Multiply both sides by 3 and you get

Subtract 160 from both sides to get

Note: you could solve this exercise very quickly if you notice that the two numbers, 86 and 74, are symmetrical with respect to 80, which is the average. So, the third number must be the average.
Y= -5/3x + 2
To find slope:
-8-7 / 6 - (-3) = -5/3
Plug in x and y from one of the points to the equation to find b
7 = -5/3 (-3) + b
B = 2
Put it all together:
y = -5/3x + 2
So, the easiest thing to do here is to add up the numbers of each option to find the number most similar to the solution of (-4/5)(3/5)(-6/7)(5/6) which is approximately equal to 0.34.
The product of expression A is -0.25
The product of expression B is 0.50
The product of expression C is 3
The product of expression D is -0.05625
So, first of all, we can rule out choices A and D because they are both negative, whereas 0.34 is not. Now, we just have B and C, and clearly, B is much closer to 0.34 than C is, so B is the correct answer. I hope this helps! :)
