The answer is that each brick weights .515 pounds.
Step-by-step explanation:
10 to the 3rd power is 10^3 = 1000 bricks.
The weight of the full truck minus the weight of the empty truck is the weight of the bricks:

Answer:
Step-by-step explanation:
<em>Parallel lines divide the transversals proportionally.</em>
Set proportions and solve for k:
- k/24 = 64/32
- k/24 = 2
- k = 24*2
- k = 48
Correct choice is E.
there's no exact answer for it because pi goes on forever
The square of a binomial expands as follows:

Expanding all the binomials, we have

Sum like terms:

Simplify terms appearing on both sides:

Move all terms involving k to the left and all numbers to the right:

Divide both sides by -20:
