Answer:
444 adult ticket
763 student ticket
Step-by-step explanation:
let a = number of adult ticket
let s = number of student ticket
s+a=1207
5a+s=2983
get s by itself in the 1st equation so you can plug it into the 2nd
s+a=1207
-a -a
s=1207-a
5a+(1207-a)=2983
solve for a
4a+1207=2983
-1207 -1207
4a= 1776
444
this is adult ticket amount
subtract this from 1207 to get student amount
1207-444=763
B the answer is B

LM + LN > MN,
LN + MN > LM</span>
Explanation:In any triangle, the sum of any two sides MUST BE GREATER than the third side.
Therefore, to decide whether the given coordinates can form a triangle or not, we will simply get the length of each side and then check the above condition.
The length can be calculated using the distance formula attached in the image.
LM =
= 39.05 units
MN =
= 31.906 units
NL =
= 22.4722 units
Now, let's check:
LM + MN = 39.05 + 31.906 = 70.956 units > NL
MN + NL = 31.906 + 22.4722 = 54.3782 > LM
LM + NL = 39.05 + 22.4722 = 61.5222 > MN
Therefore,, the given coordinates can form a triangle
Hope this helps :)
