A total of 564 tickets were sold for the school play. they were either adult tickets or student tickets. there were 64 more students tickets sold than adult tickets. how many adult tickets were sold?

Let Adult tickets be  a.

Student tickets were 64 more than adults

= a + 64 Total = 564

a + a + 64 = 564

2a + 64 = 564

2a = 500a =

500/2a = 250

Recall a represents adult tickets.

a = 251, Therefore 251 adult tickets were sold.

Step-by-step explanation:

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
