Answer:
60 ; - 40 ; 22 ; - 11
Step-by-step explanation:
Given that:
Number of questions = 20
Rules :
Every correct answer scores 3 points.
Each incorrect answer loses 2 points.
A question not answered scores 0 points.
It is possible to finish the quiz with a negative score.
a)
Maximum score : answering all questions correctly :
(3 points * 20 questions)
= 3 * 20
= 60 points
b)
Minimum score is obtainable by answering all questions incorrectly ;
(-2 points * 20)
= - 40 points
c)
10 correct answers = (3 * 10) = 30 points
(14 - 10) = 4 incorrect answers = (-2 * 4) = - 8 points
Net total = 30 + (-8) = 30 - 8 = 22 points
d) Another student answers 18 questions,
5 are correct. How many points does she score?
5 correct answers = (5 * 3) = 15 points
(18 - 5) incorrect answers = (13 * - 2) = - 26 points
Net total = 15 + (-26) = - 11 points
Step-by-step explanation:
Simplification
=3x -x +14 -15
= 2x - 1
3x + 2y = 2, -2x + y = 8
Let us just solve by testing each of the options.
Option A is (-2, 4), that is x =-2 and y = 4
check: for x = -2 and y = 4
3x + 2y = 2
3*-2 + 2*4
-6 + 8 = 2
2 = 2
So both sides are equal.
-2x + y = 8 x = -2 and y = 4
-2*-2 + 4
4 + 4
8
8 = 8
Since option A (-2, 4) satisfies both equation, no need to test other options.
Option A is the answer.
