a total of 548 tickets were sold for the school play. they were either adult tickets or student tickets. the number of student tickets sold was three times the
number of adult tickets sold. how many adult tickets were sold?

137 adult tickets were sold

Step-by-step explanation: Total - 548

Adult - x; Student 3x. Make a equation:

3x+x=548

4x=548

x=548/4

x= 137 - adult

137*3= 411 student

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
