For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
We now write the expression that models the problem:
From here, we clear the value of x.
We have then:
Answer:
4/9 divided by 1/27 equals 12
Given :
Two equations :
-8x + 3y = -17 ....1)
3x - y = 7 ....2)
To Find :
The solution of the system.
Solution :
Multiplying equation 2) by 3 and adding with equation 1), we get :
(-8x + 3y) + 3(3x - y) = -17 + 21
x = 4
Putting above value of x equation 2) we get :
12 - y = 7
y = 5
Therefore, solution of system is ( 4,5 ).
Answer:
Step-by-step explanation:
Prime numbers are number that can only be divided by itself and 1.
E.g 2,3,5,7,11,13,17,19,23,29 etc.
So, note that this sequence doesn't have a pattern, it is neither Geometry Progression nor Arithmetic Progression.
Now, let take look at the model given
If n is prime, then 2n-1 is prime
Let take 5 for
n=5 is a prime number
2n-1=2(5)-1=10-1=9
9 is not a prime number so the model doesn't work
A prime number doesn't have sequence so, it cannot be model with sequence.
I hope this help
