47 times 22 = 1034
1034/2 = 517
380 is less than 517 so Renee has more than enough for each student.
5x+y=2
4x+y=4
5x+y=2
-1( 4x+y=2)
5x+y=2
-4x-y=2
your y'all cancel out so you r left with
x=-2
then you plug the x in to one of the equations
5(-2)+y=2
-10+y=2
then add 10 to both sides
y=12
Answer: x = -2 y = 12
there's the work and all its simple you just have to figure out how to get rid of y or x ( which ever is easier) and you can figure it out after that
The bus b can travel 85 miles make calculation the 3 hours - 85
It will have to be 60 * Degree
Yes
Y=15/x or xy=15 it seems that a should be 15/x
