Answer:
x=-2.2 y=-1.6
Step-by-step explanation:
8x+y=-16
-3x+y=5
5x=-11
x=-11/5 or -2.2
-3x+y=5
-3(-2.2)+y=5
6.6+y=5
-6.6+y=-6.6
y=-1.6
Answer:
50 cm^2
Step-by-step explanation:
The volume of a square pyramid can be found using:
v= 1/3 bh
Where b is the area of the base, and h is the height
First, we have to find the area of the base
a=l*w
In a square, all sides are equal, so we know the length and the width are both 5
a=5*5
a=25
Now, we can substitute 25 in for b, and 6 in for h
v=1/3bh
v=1/3(25*6)
v=1/3(150)
v=50
Volume uses units cubed, and in this case our units are centimeters
The volume is 50 cm^3
