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 .
You can use the prefixes to figure this out:
Mono: one
Bi: two
Tri: three
So, because there is only one term, it is a monomial.
Let the two numbers be x and y.
The sum is 45, therefore
x + y = 45 (1)
The difference is 5, therefore
x - y = 5 (2)
Add equations (1) and (2).
x + y + (x - y) = 45 + 5
2x = 50
x = 25
From (1), obtain
25 + y = 45
y = 45 - 25 = 20
Answer: 20 and 25
Answer:
<h2><u><em>
x = 6</em></u></h2>
Step-by-step explanation:
they are two opposite angles, therefore equal
14x - 4 = 13x + 2
14x - 13x = 2 + 4
x = 6
-----------------
check
14 * 6 - 4 = 13 * 6 + 2
80 = 80
<em>the answer is good</em>
