8 ÷ (2/3)
Divide 2/3 first, because it's in the parenthesis.
Divide 8 by the product of 2/3 = 12.
The answer to the question
15^2 + 8^2 = 225 + 64 = 289
square root 289 = 17
answer
<span>length of the hypotenuse of the triangle = 17 cm (3rd choice)</span>
<span>The underlined place in 83.5851 which is then rounded to the nearest thousandth is </span>A. tenth; 83.585 .
If he answered 3 questions correctly, then the number of questions is got wrong is 7 and the number of questions that he did not attempt is 5.
<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
