D is equivalent because brackets don’t change anything here
Kevin painted of the wall.
Solution:
Fraction of the wall painted by Elena =
Fraction of the wall painted by Matthew =
Fraction of the wall painted by Kevin = ?
Full wall can be taken as 1.
<u>To find the wall painted by Kevin:</u>
Rest of the wall = Full wall – painted by Elena – Painted by Matthew
To make the denominator same, multiply the numerator and denominator of the first term by 9.
Rest of the wall =
Hence the kevin painted of the wall.
So, I think that your answer will be D because it has to end at a degree of 180
So your goal is to set it equal to Y, so you have to start by subtracting k and you get t-k, then you have to get rid of the fraction by multiplying both sides by the denominator (n), so then you get n(t-k) and the only thing left is to divide by the e, and you get 4
I believe it's r I'm really sorry if its wrong
