Answer:
I think it is D. Becuase you have to simplify the numarater then the demonater.
Let unknown number be x.
Given,
7x - 8 = 3x + 4
4x = 12
x = 3
Hence, the number is 3.
(-1,4)(2,6)
slope = (6 - 4) / (2 - (-1) = 2 / (2 + 1) = 2/3 <==
Qt = 16.
Because since rs Is equal to qr since r is the midpoint of qs. So qr is 8 and because s is the midpoint of the whole line. I multiply it by 2. Giving me 16 for the whole line
Simple add them all 2+7+3+7+9 is 28 then divide 28 by the amount of numbers (5) to get 5.6 or if you are rounding to the nearest number 6... Hope this helped ;)
