Answer:
170
Step-by-step explanation:
Given
Tickets = $2 per single and $3 per couple
Total tickets = 365
Total receipts = $925
Required
Number of singles tickets sold.
Let S and C represent singles and couples respectively.
If the total number of tickets sold is 365, then
S + C = 365 --- (1)
Also, if the singles are charged $2 and couples, $3, then
2S + 3C = 925 ----- (2)
Make C the subject of formula in (1)
C = 365 - S
Substitute 365 - S for C in (2)
2S + 3(365 - S) = 925
Open bracket
2S + 1095 - 3S = 925
Collect like terms
2S - 3S = 925 - 1095
-S = -170
Multiply both sides by -1
-1 * -S = -1 * -170
S = 170
Recall that S represents number of single present at the even.
Hence, the number of singles are 170
Answer:
the correct one is c, which is the second option
Step-by-step explanation:
The exterior angle of a polygon is 360.
And for a rectangle, they have equal exterior angles.
So a rectangle has 4 sides
So each exterior angle=360/4
Then each is 90°
Then the correct c which has 90°
the answer for this is 84915
F(-2)+g(5) = 3(-2) -1 + (-5) + 6
f(-2)+g(5) = -6 -1 - 5 + 6
f(-2)+g(5) = -6
