kaheart [24]

$\\ \sf\longmapsto \dfrac{8}{12}=\dfrac{x}{9}$

$\\ \sf\longmapsto 12x=8(9)$

$\\ \sf\longmapsto 12x=72$

$\\ \sf\longmapsto x=\dfrac{72}{12}$

$\\ \sf\longmapsto x=6$

raketka [301]

Hi! So what this is asking for is how LONG the line is, not how tall. So you see B. It is on 0. And you go to A, it is on 6. Zero from 6 is 6. So 6 is your answer.

In a test (+5) marks are given for every correct answer and (-2) marks are given for every incorrect answer . Roy answered all t

katovenus [111]

Answer:

20 questions

Step-by-step explanation:

Given

$Correct \Marks= +5$

$Incorrect\ Marks= -2$

$Score\ Obtained = 30$

$Number\ of\ correct\ answers = 10$

Required

Number of questions answered

First, we need to get the total correct marks obtained by Roy

This is calculated by multiplying the correct marks by number of correct answers

$Total = +5 * 10$

$Total = +50\ marks$

Subtract this from the total scores obtained; This gives the total incorrect answer obtained by Roy

$Incorrect = Scores\ Obtained - Total$

$Incorrect = 30 - (+50)$

Open bracket

$Incorrect = 30 - 50$

$Incorrect = -20$

Divide this by -2 to get the number of incorrect answers

$Incorrect\ Answers = \frac{-20}{-2}$

$Incorrect\ Answers = 10$

Add this to the number of correct answers to give the total number of question answered

$Total = Correct\ Answers + Incorrect\ Answers$

$Total = 10 + 10$

$Total = 20$

<em>Hence, Roy answered a total of 20 questions</em>
