A school theater can sell 35 tickets for a show. If 28 have been sold, how many tickets are still left to be sold?

A: 63
B: 17
C: 7
D: 108

C: 7

Step-by-step explanation:

Total number of tickets = 35

Tickets sold = 28

Tickets left = 35 - 28

Answer = 7

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
