PT = TQ
Given PT = 4x - 6 and TQ = 3x + 4
so
4x - 6 = 3x + 4
Subtract 3x from both sides
4x - 6 - 3x = 3x + 4 - 3x
Simplifying
x - 6 = 4
Add 6 to both sides
x - 6 + 6 = 4 + 6
Simplifying
x = 10
PT = 4(10) - 6 = 40 - 6
PT = 34
Answer
PT = 34
I am pretty sure that it is just 7. since (-7)^2 is 49 and (-7)^-1 should be 7 and 49/7=7
(you might want to double check with a calculator)
We are not given a specific group that was surveyed, so all we would do is add all the students.
32 + 23 + 31 + 12 + 8 + 30 + 11 = 154
We end up with 154 students that were surveyed.
