Do you mean X is A.
BTW did you get the question from Khan Academy.
F(-11/5) if f(n) = 5n + 6.
f (-11/5) = 5 (-11/5) + 6
f (-11/5) = -11 + 6
f(-11/5) = -5 :)
Answer:
609 males
Step-by-step explanation:
A city council organized a marathon race to promote good health.
Let the number of
Females = x
Males = y
There were 3 times as many female participants as male participants in the marathon.
3x = y
If the total number of participants was 812,
x + y = 812..... Equation 1
We substitute 3x for y in Equation 1
x + 3x = 812
4x = 812
x= 812/4
x = 203 females
3x = y
Solving for y
3(203) = 609 males
The number of males participants = 609
