Answer:
B. 6
Step-by-step explanation:
The volume is proportional to the height. The ratio of the heights of the taller to shorter pyramids is 6 : 1. Since the pyramids have the same base ares, this is also the ratio of volumes.
The volume ratio is 6.
Step-by-step explanation:
lets separate z from each equation
2z=x-2y-2
4z=5x+2y+2
5z=-5y
so
z=x/2-y-1
z=5x/4+y/2+1/2
z=-y
lets use the first and third equation
we have z=-y we replace this z at the first equation
-y=x/2-y-1 so x/2-1=0
x/2=1
x=2
now we replace z=-y and x=2 at the second equation so
-y=5*2/4+y/2+1/2
-y/2-y=5/2+1/2
-3y/2=6/2
-3y/2=3
-y/2=1
y=-2
we know that z=-y
so z =-(-2)=2
finaly we have that
x=2 ,y=-2 ,z=2
Answer:
106
Step-by-step explanation:
Bring the values to one side and change the signs
Always substitute in brackets
_=136+(-30)
106=136-30
Thus your answer is 106
