Hello!

It tells you what to do in the question

First round all the numbers to the nearest whole number

2.20 = 2
2.34 = 2
2.7 = 3

Then it says to multiply all the numbers

2 * 2 * 3 = 12

Then it says to divide by 6

12 /  6 = 2

The answer is 2 cubic yards

Hope this helps!

The estimated volume would 2 cubic yds

the volume of any pyramid is defined by V = (1/3)Bh  where B is the area of the base of the pyramid and h is the height of the pyramid.  

Here: 
B = (.5)(3)(2) = 3  rounding the dimensions of the base
h = 2 rounded
So volume would be V = (1/3)(3)(2) = 2 cubic yds <span />

Solve the systems of equations 6x+3y=9 2x+3y=1
patriot [66]
Solve by elimination.
The goal is to cancel out one of the variables in order to easily solve for the other variable.

Do this by changing the equations so that the coefficients of either x or y add up to 0.

Notice the coefficients of y are 3 and 3, if we make one of them negative then they add up to 0. 3+ (-3) = 0

Multiply 2nd equation by -1.

6x +3y = 9
-2x -3y = -1
__________
4x +0y = 8

Solve for x
4x = 8
x = 8/4 = 2

Plug x=2 back into one of original equations to find y.
---> 2(2) + 3y = 1
---> 4 + 3y = 1
---> 3y = -3
---> y = -1

Therefore solution is (2,-1)
