shusha [124]

Let L represent lower level tickets and U upper level.

Starter equations:
L + U = 2368
78L + 59U = 157800

Solve simultaneous equations:
59L + 59U = 139712
so 19L = 18088
L = 952
U = 2368 - 952 = 1416

952 lower level tickets and 1416 upper level tickets were sold.

If possible, draw a line of symmetry in each of the following figures or words. If it is not possible to draw a line of symmetry

Marrrta [24]

Answer:

a) none

b) vertical through the middle

c) horizontal through the middle

d) none

Step-by-step explanation:

a) A repeated asymmetrical pattern rarely has a line of symmetry. (I can't think of a case where it does.)

b) This figure has left-right symmetry about its centerline. (In general, a light bulb will not, because the screw threads are asymmetrical.)

c) Each of the letters is symmetrical about its horizontal centerline, so the word is as well.

d) The letter S is symmetrical about its center point, but not about any horizontal or vertical line. This word is not symmetrical about any line.
