Answer:
8 pencils per student.
Step-by-step explanation:
Since there are 4000 pencils and 500 students we can do 500 divided by 4000 to get our rate, 8 pencils for every student.
Answer:
1) 3( 2) - 1 = 6 - 1 = 5
2) 2(-1) - 3+4(-1) = -2 -7 = -9
3) 4^2-6(4)=9 = 16-24=9, = -8=9
Answer:
C
Step-by-step explanation:
Hopefully this helps, Idk how well to explain it but Im pretty sure its C if not tell me! :)
y = 8 -2x
x + 2 (8 - 2x) = 1
x + 16 - 4x = 1
x - 4x = -15
-3x = -15
x = 5
If x = 5, then we can substitute in...
5 + 2y = 1
2y = -4
y = -2
Now let us check that by substituting those values in to the equation
2x + y = 8
2 (5) + (-2) = 8
That is correct so we have the right values for x and y/
Cone volume - V=pi r^2 h/3
r= radius
h= height
cylinder volume - V=pi r^2 h
r= radius
h= height
the cylinder is 3 times the volume of the cone.
