Answer:
h=123,200
Step-by-step explanation:
First you must in the formula for the pyramid, which is

and as far as the question has gave us
V=18069333.33333
LW=440
1.) Plug those numbers into the the equation, which should be:

2.) Then isolate the "h" by dividing both sides by
, or multiplying its reciprocal, which is 

3.) Simplify or round the numbers if you need to.

Answer:
45 marbles
Step-by-step explanation:
Using the information provided, we can form the equation x/5 - 2 = 7
Step 1: Add two on both sides of the equation x/5 - 2 = 7
Step 2: Multiply both sides of the equation by 5, to cancel out x. x/5=9
Step 3: Lastly, you get that x=45 marbles
Answer:
B.
Step-by-step explanation:

Correct answer is the 4th choice 16!!!
Hope this helps!!!
The answer is $1.80. You would take 25% of 3, which is 75, and subtract it from 3. That leaves you with $2.25, which you take 20% off, which is 0.45, and subtract that from 2.25. That leaves you with a grand total of $1.80. Hope that this helped!
