Kiran read for x minutes, and Andre read for 5/8 more than that. Write an equation that relates the number of minutes Kiran read
2 answers:
Answer:
Step-by-step explanation:
Here x represents the time taken by Kiran in reading (in minutes) and y represents the time taken by Andrew in reading (in minutes).
According to the question,
Andre read for 5/8 more than kiran.
Thus, The time taken by Andrew(in minutes) = time taken by kiran + 5/8 of time taken by kiran
=
=
=
=
Thus, required equation,
Answer:
The required equation is
Step-by-step explanation:
Given : Kiran read for x minutes, and Andre read for 5/8 more than that.
To find : Write an equation that relates the number of minutes Kiran read with y, the number of minutes that Andre read ?
Solution :
The number of minutes read by Kiran = 'x' minutes.
The number of minutes read by Andre = 'y' minutes.
Andre read for more than that,
The number of minutes Kiran read to the number of minutes that Andre read is given by,
Therefore, The required equation is

<h2>Answer:</h2>
Figure B
<h2>Step-by-step explanation:</h2>The Pythagorean Theorem is , where c is the longest side of the triangle (the hypotenuse).
To find the side length of each square, you have to square root the area of each square. This means that Figure A has side lengths of 3, 6 and 8 units. Figure B has side lengths of 5, 12 and 13 units.
In Figure A, if the triangle is right-angled, the equation must be correct. 9 + 36 = 45. 45 is not equal to 64, so the triangle is not right-angled.
In Figure B, if the triangle is right-angled, the equation must be correct. 25 + 144 = 169. 169 is 13 squared, so the triangle is right-angled.
Alternatively, as you are already given the square values for each side length, there is no need to square root and square again. You can just test if the two smaller areas equal the larger area, but the explanation above uses a more detailed example of the Pythagorean Theorem.
