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:

Step-by-step explanation:
Let the number be x.
Translating the word problem into an algebraic equation, we have;
Opening the bracket, we have;

Collecting like terms, we have;

Answer:
(0,8)
Step-by-step explanation:
-2x+y=5
x-3y=-30 so you can multiply the bottom equation by 2 you'll get 2x-6y=-60
-2x+y=5
2x-6y=-60 And subtract the equations. You'll get -5y=-55 y=11. Plug it in to one of the original equations. -2x+(11)=5
-2x=-6 so x=3
y=11 and x=3
= [7+7 <span>÷ 7] + 4.12
= [7+1] + 4.12
= 8 + 4.12
= 12.12
