Understanding zero as a number represented by the symbol 0 enabled mathematicians to have a representation of nothing. Having a digit to represent zero enables mathematics to be more abstract, and allows more complex problems to be solved.
This is a ratio problem. You only need solve the ratio of the sand.
<u> 48 </u> <u /> = <u> n </u> <u />
1 156
(48)(156) = 1(n) (cross multiplying)<span>
</span>
7,488 pounds
To check: The pool deck is 156 times larger than the original amount of concrete so the amount of sand needs to be 156 times more.

Answer:
(20 - 24)/6
Step-by-step explanation:
We have the algebraic expression
6(x + 4)= 20
We expand the brackets
6x + 24 = 20
Collect like terms
6x = 20 - 24
x = (20 - 24)/6
A correct solution to the expression is
(20 - 24)/6
