47/4 is your final answer
Answer:
4 inches
Step-by-step explanation:
The volume of a cube is given by
V = s^3 where s is the side length
64 = s^3
Take the cube root of each side
(64)^ 1/3 = (s^3) ^1/3
4 = s
Answer:
(7, 3)
Step-by-step explanation:
get rid of the y by adding:
x=-2
+x=16
then add the equalities:
2x=14
divide by 2:
x=7
then subsitute the x in to find y!
7+3y=16
3y=16-7
3y=9
y=3
Unless there is no promotion like "buy 2 get 1 free" or "buy 2 get 1 for 50%" etc. then the cost of ordering multiple items is always proportional. Let's say something costs $5. Two items will cost $10, three $15, four $20 etc. These numbers are all proportional. Hopefully that's what you meant :)
