6 + 2 = 12
When 2 = 3
Change the equation to: 6 + 3
So,
6 + 3 = 9
You're answer is 9
Answer:
5 cubes
Step-by-step explanation:
The volume of a square pyramid is given in terms of its side length (s) and height (h) as ...
V = (1/3)s^2·h
For the given measurements, the volume is ...
V = (1/3)(9 cm)^2 ·(10 cm) = 270 cm^3
___
The volume of each cube of wax is the product of its length, width, and height, so is ...
V = (4 cm)^3 = 64 cm^3
___
Then the number of wax cubes required to fill the pyramid is ...
(270 cm^3)/(64 cm^3/cube) = 4 7/32 cubes
Four cubes are not quite enough to make the candle.
Devin will need 5 cubes to make the candle.
Answer:
x = 9/2 y = 0
Step-by-step explanation:
2/3x + 5y = 3 5y = -2/3x + 3 y = -2/15x + 3/5
4/3x - 2(-2/15x + 3/5) = 6
4/3x + 4/15x - 6/5 = 6
8/5x - 6/5 = 6
8/5x = 36/5
x = 9/2
2/3(9/2) + 5y = 3
3 + 5y = 3
5y = 0
y = 0
