Answer:
The player answer correctly 30 questions
Step-by-step explanation:
First we have to develop the information that gives us as 2 equations
x = correct answer
y = incorrect answer
z = score = 40
h = total answer = 50
2x - y = z x + y = h
2x - y = 40 x + y = 50
we clear the x of one equation and replace the value of x in the other equation
x = 50 - y
2x - y = 40
2(50 - y) - y = 40
100 - 2y - y = 40
-3y = 40 -100
y = -60/-3
y = 20
x = 50 - y
x = 50 - 20
x = 30

Answer:
6:5
Step-by-step explanation:
6:5 is already at its simplest form.
You cannot simplify 5 anymore than it is.
But, it can be written as 1.2 in decimal form (rounded to 6 decimal places).
Though, I do not believe that is the answer you are looking for.
All you have to do is divided 43.54 divided by 3.5 which is 12.44 mph
