A total of 234 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?

Answers

234 = a + s                                                       s = students       a = adults
2a = s
after you get the equations you solve. plug 2a into the above equation.
so u get 
234 = a + 2a 
234=3a then divide 3 from each side
78 = a
so 78 adult tickets were sold

What two numbers add to equal -11 and multiply to equal 28?What two numbers add to equal -20 and multiply to equal 51?
What two numbers add to equal -5 and multiply to equal -36?

Answers

-4 + -7 = -11      4 * 7 = 28
-17 + -3 = -20    17 * 3 = 51
4 + -9 = - 5      4 * -9 = 36
the answer for first is -4 and -7 (-4 + -7) = 11 , -4 x -7 = 28

The answer to the second is -17 and -3 (-17+-3) = 20,  -17 x -3 = 51

The answer to the third is -9 and 4  ( -9 + 4)  = -5 , -9 x 4 = -36
