Answer:
Step-by-step explanation:
4y - 2(5 - y + 4) = 4y - 2(9 - y)
= 4y + 9*(-2) - y *(-2)
= 4y - 18 + 2y {Combine like terms 4y and 2y}
= 6y - 18
6y - 18 = 6*y - 6*3
= 6(y - 3)
6y- 18 = 2 *3y - 2*9
= 2(3y -9)
2(3y - 9) and 6(y- 3 ) are equivalent to 4y - 2(5- y +4)
Others are not equivalent
Well you see that they are all 2 so go on to the next part you have two 2.9 and two 2.8 . since the 2.8 s are smaller you continue with them and you have a 2.83 and a 2.84; 3 is smaller than 4 so the 2.830 will be the least and the 2.841 will come next. now you go back to those 2.9 s and continue. you have a 2.91 and a 2.90. 0 is less than 1 so 2.909 will come next and 2.912 will be last .
2.830; 2.841; 2.909; 2.912
N is the same as 17, so it equals 17.
