Answer:
Senior citizen tickets = 9
Student tickets = 10
Step-by-step explanation:
We begin by converting the question into simultaneous linear equations;
Senior citizen tickets = a
Student tickets = b
4a + 6b = 96
8a + 13b = 202
to find a,
if 4a +6b = 96
a = 96/4 - 6b/4
a = 24 - 1.5b
We now substitute this into the second equation
8(24 - 1.5b) + 13b = 202
192 - 12b + 13b = 202
b = 202 - 192
b = 10
We now put the value of b in either equation
4a + 6b = 96
4a + 6(10) = 96
4a + 60 = 96
4a = 96 - 60
4a = 36
a = 9
17) -3 + x > 19
x > 19 +3
x > 22
18) -3 <_ 6x - 1
(Here, please note that <_ is lesser than or equal to and >_ is greater than or equal to)
6x >_ -2
x >_ -1/3
19, 20, 21) now onward Ima type just the answers -_-
x > -7/2
x < 12
x<_ 2
A number that is a factor of 16 and is prime would be 2.
2 x 8 = 16 (So it's a factor of 16)
Hope this helps! :D
