Explanation:
As we know that set is the collection of elements and set builder is the method of defining the set with the help of specific property in which we can use arithmetic operations as well
Generally,
It is the general form of any set in which we can construct the complete set with the help of equation in the given in set builder form.
Since we have the elements : 45,55,65,75
So, the set builder form will be { x: x =5(2n+1) ,4≤n≤7,x,n∈ N }
We will read it as it is the value of x which will be find with the help of given equation i.e. x=5(2n+1) where n goes from 4 to 7 only and x and n are natural numbers only.
Answer:
the answer is in the imagen
Step-by-step explanation:
3x-34=2x-5 so x is equal to 29
Answer:

Step-by-step explanation:
Given that two companies have sent representatives to an industry conference.
The first company sent 12 representatives and the second company sent 20 representatives
Selecting any 22 out of these 32 can be done in 
Favourable outcomes = No of ways of selecting 10 from I and 12 from II
= 
Probability required = 
Answer:
<em>Hey mate, here's ur answer:</em>
<em>----------------------------------------------------------</em>
<em>(4a - 3b + 4c) + (8a - 2b + 3c)</em>
=4a+−3b+4c+8a+−2b+3c
=(4a+8a)+(−3b+−2b)+(4c+3c)
<u>=12a−5b+7c</u>
