Cy +y=d - 4
y(c+1)=d-4
y=d-4/c+1
He drinks 8 glasses of water in one day. to know the number of glasses he drinks in 365 days, simply use cross multiplication as follows:
number of glasses per year = (365*8)/1 = 2920 glasses
so, yes his assumption is reasonable if he kept the same rate (8 glasses per day each day)
Answer:
1/12 (or 0.833)
Step-by-step explanation:
Recall that the definition of "slope" is the change in vertical distance divided by the change in the horizontal distance. (aka. rise ÷ run)
it is given that rise = 50 feet and the horizontal distance (i.,e "run") = 600feet
hence slope = rise / run = 50 / 600 = 1/12 (or 0.833)
