Common ratio, r = (3/2)/(3/20) = 10.
3/20, 3/2, 15,
4th term = 15*10 = 150
5th term = 150*10 = 1500
5th term = 1500
Answer:
OPTION B: K = 15
Step-by-step explanation:
The given equation is: 21 + 3x = 3x + K
Substitute K = 3x
we get: 21 = 3x + 3x + 3x
⇒ 21 + 3x = 6x
⇒ 21 = 3x
This gives the value of x = 7. That means K = 3x gives us a solution. So, OPTION A is eliminated.
Now, K = 15
The equation becomes 21 + 3x = 3x + 15
Subtracting 3x on both the sides, we get:
⇒ 21 + 3x - 3x = 15 + 3x - 3x
⇒ 21 = 15 which can not be correct. So, K = 15 renders the equation meaningless and hence with no solution.
So, OPTION B is the answer.
Note that K = 21 will give the equation with infinitely many solutions.
Answer: B) 1/6•3=1/2
Step-by-step explanation:
quotient means division
which means 1/2 / 3
which equals 1/6
This is the only equation with 1/2, 3, and 1/6
The answer is $2.90
Hope that helps
