The contestants total number of points is 20.
30 + 15 = 45
45 - 25 = 20 total points
Answer:29
Step-by-step explanation:
Opposite angles in a quadrilateral (the trapezium inside the circle) must add up to 180, so 180-92 = 88.
So DAB = 88
Angles on a straight line add up to 180, so to find t, you have to 180 - 88 - 63 = 29
So t is 29.

we are given
where
price p( in dollars) of a new smartphone
t is the number of months since January
now, we can solve for t
step-1:
Add both sides by 4t^2
step-2:
Subtract both sides by p
step-3:
divide both sides by 4
step-4:
Take sqrt both sides
so, we get
..............Answer
Simplify the equation to n-6=4n+18
subtract 4n from both sides
n-6-4n=4n+18-4n
-3n-6=18
add 6 to both sides
-3n-6+6=18+6
-3n=24
divide both sides by -3
-3n/3=24/-3.
n=-8
hope this helps!
