I need to know the equations
dem82 [27]
Let l, t, b represent the numbers of lions, tigers, bears, respectively.

2l +3t +3b = 156 . . . . . . . 156 meals per day are supplied
l +t = 3b . . . . . . . . . . . . . . there are 3 times as many great cats as bears
l +t +b = 68 . . . . . . . . . . . there are a total of 68 animals

_____
The last 2 equations tell you
.. 4b = 68
.. b = 17
Subtracting 3 times the last equation from the first gives
.. -l = -48
There are 48 lions, 3 tigers, and 17 bears.

Which statements are true regarding the prism ?
DochEvi [55]

Answer:

Step-by-step explanation:The prism has 9 edges; the bases of the prism are triangles; and the prism has 5 faces.

Step-by-step explanation:

The bases of a prism are the faces that are parallel.  In this prism, the only faces that are parallel are the two triangles.  This means the bases are triangles.

In addition to the two parallel bases, there is a are three faces that join the sides of the bases.  This makes a total of 2+3 = 5 faces.

The edges are where the faces meet.  There are 3 edges around each base; this is 6.  There are also 3 edges connecting the lateral faces; this makes 6+3 = 9 edges.
