in an academic contest, correct answers earn 12 points and incorrect answers lose 5 points. In the final round, School A starts with 165 points and given the same number of correct and incorrect answers. School B starts with 65 points and given no incorrect answers and the same number of correct answers as School A. The game ends with the Schools tied.
Part A: Which equation models the scoring in the final round and the outcome of the contest?
A.) 12x + 5x - 165 = -12x + 65
B.) 12x - 5x + 165 = 12x + 65
C.) 5x - 12x + 165 = 12x + 65
D.) 12x - 5x - 165 = 12x +65
Part B: How many answers did each school get correct in the final round?
Answers
Answer:
part a is b part b is 230 tell me if im wrong
Step-by-step explanation:
Step-by-step explanation:
Let x represent the number of correct answers School A gave.
Then x is also the number of incorrect answers School A gave and the number of correct answers School B gave.
Final score of School A
= 165 + 12x - 5x.
Final score of School B
= 65 + 12x
Hence the correct equation is
12x - 5x + 165 = 12x + 65. (B)
=> 7x + 165 = 12x + 65
=> 5x = 100
=> x = 20
Hence Schools A and B got 20 correct answers each.
To the nearest tenth, what is the perimeter of the triangle with vertices at (−2, 3), (3, 6), and (2, −2)?
Answers
9514 1404 393
Answer:
20.3
Step-by-step explanation:
The distance formula can be used to find the side lengths.
d = √((x2 -x1)^2 +(y2 -y1)^2)
For the first two points, ...
d = √((3 -(-2))^2 +(6 -3)^2) = √(5^2 +3^2) = √34 ≈ 5.83
For the next two points, ...
d = √((2 -3)^2 +(-2-6)^2) = √(1 +64) = √65 ≈ 8.06
For the last and first points, ...
d = √((-2-2)^2 +(3-(-2)^2) = √(16 +25) = √41 ≈ 6.40
Then the sum of the side lengths is ...
5.83 +8.06 +6.40 = 20.29 ≈ 20.3
The perimeter of the triangle is about 20.3 units.

the lager value of y for which (y-1)²=4y-7 is
Answers
Answer:
the lager value of y is 4.
Step-by-step explanation:
Given;
(y-1)² = 4y - 7
Simplify as follows;
(y - 1)(y - 1) = 4y - 7
y² - y - y + 1 = 4y - 7
y² - 2y + 1 = 4y - 7
Collect like terms
y² -2y - 4y + 1 + 7 = 0
y² - 6y + 8 = 0
Factorize the equation;
y² -2y - 4y + 8 = 0
y(y - 2) -4(y - 2) = 0
(y - 2)(y - 4) = 0
y = 2 or y = 4
Thus, the lager value of y is 4.
20 points!
