18 square units should be the right answer
Solution:
Let each pond of jelly beans cost $x.
and each pond of almonds cost $y.
Then we can write


Now solve these two equations together using substitution we get


Hence each pond of jelly bean cost 1.25$
Each pond of almond costs 2.25$
-7x+12-2x=23+13x
First take away 13x from the right side and put it on the left side adding taking it away from -7x
-7x(-13x)=-20x
-20x+12-2x=23
then add 2x to -20x
and move 12 to the other side, minus it off of 23
-18x=11
then divide -18x on both sides
then x=-11/18
Answer:
88 
Step-by-step explanation:
Given 3 measurements 6,11,4
Assuming them to be length, width and height of pyramid
⇒
Length= 6 cm
Width= 11cm
Height= 4 cm
⇒

Therefore Volume of Given Pyramid
=
⇒Volume of pyramid=88
