11.6 rounded to the nearest whole is 12 and 4.1 rounded to the nearest whole is 4 (rule is if the decimal [or number in general] is 4 or lower, the whole stays the same and if the number is 5 or higher, the whole goes up by one). 12+4=16
it is going to take 18 miles in 1 hour
We can readily know the x^2-4x+4=3y then use it to replace the same function in the first equation which refers to the 3y+y^2-6y=0
y^2-3y=0
y(y-3)=0
y1=0 -----------y2=3
48 ÷ 6 = 8
16 ÷ 2 = 8
So you need 8 vans
I hope that helps!
Well this one is very simple. It seems to give 1 lb per 4 dollars spent. So, the best way to state this mathematically is x=4y or x=4×y.
