Answer:
lets call the children, c, and call adult, a,
c+a= 52 eq 1: a=52-c
c=3a eq 2
take a's value from eq 1 and plug it into eq 2
c=3(52-c)
c=156-3c
4c=156
c=39 the number of children that attended the ball game.
Step-by-step explanation:
Answer: B
Step-by-step explanation:
(f/g) means to divide f(x) by g(x).

To find the domain, you set the domain equal to zero and solve for x.
3x-5=0 [add both sides by 5]
3x=5 [divide both sides by 3]
x=5/3
Now, we know that B is the correct answer.
Answer: 750 Joules.
Step-by-step explanation:
Use the equation: K = 1/2 x m x s^2
1/2 x 60 = 30.
30 x (5 x 5) 25 = 750
Lance's kinetic energy when he runs at this speed is 750 Joules.
