Answer:
18 cups of lemonade
Step-by-step explanation:
so if it cost him $0.15 to make each cup of lemonade and he sold a cup for $0.35 then he sold 18 cups
distance = speed * time
the first bus speed = x
second bus = x - 12
the sum of distance = 765 miles
first distance = 6x
second distance = 6 (x -12)
6x + 6(x-12) = 765
x + x -12 = 127.5
2x = 139.5
x = 69.75 mi/h which is the faster bus
the second bus speed = 57.75 mi/h
Answer: (18/5) * 11
Step-by-step explanation:
In equations of proportion, to proceed, we need to determine the constant of proportion, let's denote as "k"
Since y ~ x
Means y=kx.
To determine the value of k, we input initial values of y and x.
Initial value of y = 18
Initial value of x = 5
The equation becomes :
18 = 5k
k = 18/5.
Now, If given the value of x as 11,to determine the value of y we go back to the equation.
y= kx
y = 18/5 * 11.
