.
Step-by-step explanation:
Given : 3.21
To find : Explain how to write the rational number.
Solution : We have given 3.21
We can remove the decimal.
We can see there are two numbers after decimal so, we write the 100 in denominator.
.
So, this is the .
a = 321 , b =100
Therefore, .

use associative property which is
(a+b)+c=a+(b+c)
also -a+b-c=(-a)+(b)+(-c) so you can move them around
and remember that:
you just use a general rule
x+x=2x
x^2+x^2=2x^2
3xy4xy=7xy
3x+4x^2=3x+4x^2
youcan only add like terms( like terms are terms that are same name like xor y are differnt, and like terms have same power exg x^2 and x^3 andx^1/2 and such

b)about how much orange juice and pop do you need to serve 15 people? 20 people?
plz say how you answered this
Answers
O : P => 2 : 5
(a) 1 liter of pop to serve 7 people
=> 5 units = 1
1 unit = 1 / 5
Orange juice => 2 units
Hence, Orange juice needed is 2 * 1 / 5 = 0.4 liters
(b) If 1 liter of pop is needed to serve 7 people, then we will need (1 / 7) * 15 for 15 people
i.e. 2.14 liters
As the ratio of O : P = 2 : 5,
5 units = 2.14
1 units = 2.14 / 5
For Orange juice, we will need 2 * 2.14 / 5 = 0.856 liters for 15 people

Answer: 10.5 (equivalent to the fraction 21/2)
To get this answer, you set 10x-15 equal to 90 and solve for x. The reason why these two angles are equal is because they are vertical angles.
10x-15 = 90
10x-15+15 = 90+15 ...... add 15 to both sides
10x = 105
10x/10 = 105/10 ...... divide both sides by 10
x = 105/10
x = 21/2 is the answer in fraction form
x = 10.5 is the answer in decimal form
You'll use what the vertical angles theorem tells you to solve this.
The vertical angles theorem says that vertical angles are congruent, which is what the angle with (10x-15) and the opposite angle (90) are.
Since they are vertical angles, they are congruent so you can set up an equation where they are equal and solve for x.
(10x-15) = 90
1. Get rid of the parentheses.
10x-15 = 90
2. Add 15 to both sides.
10x = 105
3. Divide both sides by 10.
x = 10.5
Answer is:
x = 10.5
