Thats easy its 7/6 hope this helps
<span>basically since 30 minutes is half of an hour, to get to a full hour you can multiply by 2, so you do that for both, 2/3 included so you get 2/3 * 2/1 4/3 is 1 1/3</span>
the angles on the opposite sides of a quadrilateral touching the circumference adds up to 180 degrees
so,
(21x-2) + (38x +5) = 180
21x+38x −2+5=180
59x+3=180
59x=177
x=3
Answer:
350 adult tickets were sold
Step-by-step explanation:
Let "a" represent the number of adult tickets sold. Then the number of student tickets is (a+69) and the total number of tickets sold is ...
a + (a+69) = 769
2a = 700 . . . . . . . . subtract 69
a = 350 . . . . . . . . . divide by 2
350 adult tickets were sold.
