In a class test of 15 questions, (+4) marks are given for every correct answer, (– 2) marks are

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

In a class test of 15 questions, (+4) marks are given for every correct answer, (– 2) marks are given for every incorrect answer, and 0 marks are given for questions that are not attempted. Punit scored (– 2) marks.

If he answered 3 questions correctly, then the number of the question are got wrong and the number of the question that he did not attempt.

Let x be the correct question and y be the incorrect question, z be the number of questions that he did not attempt, and A be the number of the total score. Then we have

4x – 2z = A

x + y + z = 15

If A = -2 and x = 3, then we have

4 × 3 – 2z = -2

      12 + 2 = 2z

              z = 7

Then the value of y will be

3 + y + 7 = 15

           y = 5

Helpp i dont understand
AnnZ [28]
Betina is 155 centimeters tall or 1 meter and 55 centimeters

1 meter = 100 centimeters
100 + 87 = 187 , Brian’s height in centimeters

Since Bonnie is 58 centimeters shorter we will subtract 187-58 which gives us 129 centimeters.

Betina is 26 centimeters taller than Bonnie so we add 26+129 =155

Therefore Betina is 155 centimeters tall or 1 meter and 55 centimeters.

Hope this helped! :)
