Answer:
y = 3/8 x -3
Step-by-step explanation:
3x - 8y = 24
Solving for y
Subtract 3x from each side
3x-3x - 8y =-3x+ 24
-8y = -3x+24
Divide each side by -8
-8y/-8 = -3x/-8 +24/-8
y = 3/8 x -3
x + 3y <= 191
x = children
y = adults (x3)
So adding those two up must be either less than or equal to 191, as that is all the Chef made.

Answer:
The driver took shorter than estimated
It took shorter by 2 hours( 120
minutes)
Step-by-step explanation:
Firstly we want to know if the drive took longer or shorter
By 2 days, the number of hours will be 2 * 24 = 48 hours ( recall 24 hours = 1 day
now , since 60 minutes give one hour, then 48 hours will me 60 * 48 = 2,880 hours
This is less than 3,000 hours
By how much?
Simply subtract the value of minutes in 48 hours from 3,000 = 3000-2880 = 120 minutes ( or two hours)
