i think you need to divide, im just here to get some more points .
F = 3m
f = 3 + 4m
Since both equations are equal to f, set them equal to each other.
3m = 3 + 4m
Subtract 4m from both sides.
-m = 3
Divide both sides by -1.
m = -3
CHECK
f = 3(-3) = -9
f = 3 + 4(-3) = -9
Answer:
1/4 or 25% chance
Step-by-step explanation:
the probability of getting each question right is 1/2, so for getting 2 questions right its 1/2 × 1/2, which is 1/4
