Hey there :)
Before translating the sentence into mathematics, let r represent 'a number'
5 times a number = 5r
2 times that number = 2r
The difference between them = 5r - 2r
* Your equation
5r - 2r
* Solving the equation
= 5r - 2r
= 3r
Answer:
The answer is 1.
Step-by-step explanation:
The number is usually in front of the variable, if there is no number, it is a 1.
1 and 2 are natural numbers
-7 belongs to set of integers
sqrt 11 is a member of the set of irrational numbers
8: 20
9: 90
I am so sorry if this is wrong. I am not good at this type of things
180 degrees. It would be half of the circle.
