In this question, they gave you the system of equations. You just need to use the two of them.
We want to find the m or the number of the multiple-choice questions. So we need to turn our last equation in the form of 'm's by translating the 'f's into 'm's.


If we know the m form of f, we can convert the second equation and find the answer:

Plug in the m value of f:

Distribute the 5:

Subtract -75 from both sides:

Combine like terms:

Divide both sides by -2:

So, we learned that the number of the multiple-choice questions is 12.
I used the person can see 49km which is my V
SO 49 = 3.5 sqrt (h)
or 49/3.5 = sqrt(h)
or sqrt(h) = 14
or h= 196
So the height is 196
Answer: Try 12 games
Step-by-step explanation:
2*3= 6
$4.75 * 12= 57
57+6=63
