4 over 9 is greater than 2 over 9 because 4/9=.4444444 and 2/9=.222222 or you could think of it like a pizza, is 2 pieces a bigger amount then 2? no 4 is more
15+2*n = 9 2*n = -6 n = -3
yes, if four quarts equals one gallon, then 9 quarts would be bigger than 2 gallons because 8 qaurts would equal to 2 gallons so 9 quarts is more than 2 gallons.
9 more than -36 = -27
9/12 is more than 1/2. 9/12 is not less than 1/2.
2x+9
2m + 9
(x+9)^2 =x^2 + 9 X^2 + 18x + 81 = X^2 +9 18X + 72 = 0 18X = -72 X =- 4

9 is 6 more than one third of itself.
15+2*n = 9 2*n = -6 n = -3
n/2 + 9≤-8n/2 ≤-17n≤-34
yes, if four quarts equals one gallon, then 9 quarts would be bigger than 2 gallons because 8 qaurts would equal to 2 gallons so 9 quarts is more than 2 gallons.
9 is more than 5.
9 more than -36 = -27
This is equivalent to (x + 3)2 = (x + 2)2 + 9. Multiplied out this is x2 + 6x + 9 = x2 + 4x + 4 + 9. Deduct x2 + 4x + 9 from each side giving 2x = 4 So x = 2 Check: (2 + 3) squared = 25 which is 9 more than (2 + 2) squared = 16.
