Answer:
a d9x9x6xx0x8x7x7x
Step-by-step eaxplanation:
3/8 cross multiply x/800 8x and 2400 divide both sides by 8 to get 300. 300 is the answer
20/2.5 = 8
So 8 movies can be shown in 20 hours.
Answer:
450
Step-by-step explanation:
Answer:
{x,y} = {8,3}
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 4y = 2x - 4
[2] y = x/2 - 1
// Plug this in for variable y in equation [1]
[1] 3x - 4•(x /2-1) = 12
[1] x = 8
// Solve equation [1] for the variable x
[1] x = 8
// By now we know this much :
x = 8
y = x/2-1
// Use the x value to solve for y
y = (/2)(8)-1 = 3
