HI + IJ = HJ

=> x + 12 + 16 + x = 20

<=> 2x + 28 = 20

<=> 2x = -8

<=> x = -4

with x = -4 => HI = - 4 + 12 = 8

Answer:

Line: y = Mx + b, passes (0, 1) => M*0 + b = 1 => b = 1

Line: y = Mx + 1, pass (2, 4) => 2M + 1 = 4 => M =3/2

=> Line: y = (3/2)x + 1

Noah has 75 marbles. Noah has more marbles. this is because 34 times 3 is equal to 102. since michelle takes 9 marbles from EACH box, 9 times 3 is 27. 102 minus 27 is 75
