Let the three numbers be x, y and z. Then x+y+z=75.
z = 2x. y = x - 9.
Eliminate y and z by substitution: x + (x - 9) + (2x) = 75
Then 4x = 75 + 9, or 4x = 84. x = 21, y = 21 - 9 = 12, and z = 2(21) = 42.
Check: Do 21, 12 and 42 add up to 75?
Answer:
75 of them are red
Step-by-step explanation:
-1, -3/4, -5/8, -1/20, 0
Keep in mind that when ordering negative numbers from least to greatest, you will have to order them backwards. Think about it in terms of the distance from the number line. -1 is the farthest away from 0, therefore the least, -3/4 is the second farthest from 0, and so on.
