Step-by-step explanation:
given that the University of Montana ski team has seven entrants in a men's downhill ski event.
The coach would like the first, second, and third places to go to the team members.
Since one member can get only one place and order counts here we use permutation
No of ways the seven team entrants achieve first, second, and third places

Triangle SUT is an isosceles triangle and you can prove this by a geometric proof.
We can set SU = ST.
2x + 11 = 11x - 16
Solve for x:
9x = 27
x = 3

in the quadratic equation 3x²+7x-4=0, which is the constant term?
Answer:
1129/200 = 5.645
Step-by-step explanation:
31/8 ÷ (x-4 1/4)=17/18 +1 5/6=17/18 +11/6=17/18 +33/18=(17+33)/18=50/18=25/9
31/8 ÷ (x-4 1/4)=25/9
x-4 1/4 = 31/8 ÷25/9 = 31/8 × 9/25 = 279/200
x = 4 1/4 + 279/200 = 17/4 + 279/200 = 850/200 + 279/200 = 1129/200 = 5.645
