Hi
(-9+V) /8 = 3
-9/8 +V/8 = 24/8
-9+V = 24
V = 24+9
V = 33
let's check : -9+33 = 24 and 24/8 = 3
Given:
The system of equations is
To find:
The missing value for which the given system of equations have infinitely many solutions.
Solution:
Let the missing value be k.
We have,
Taking all the terms on the left side, the given equations can be rewritten as
The system of equations 
and 
have infinitely many solutions if
We have,
Now,
On cross multiplication, we get
Therefore, the missing value is -10.
So basically, we are looking for the amount of tip that the rider gave the driver if the driver paid a total of 23.25 dollars. So in order to get the tip, we just have to multiply the total cost of the taxi, which is 23.25, to the percentage of the tip which is 15%. So in order to get the final answer, we have to express the formula as this. 23.25 x 0.15. So if we would solve this equation, we will get an answer of 3.4875. So the tip that was given was 3.4875
Answer:
The correct answer is B
