Answer:
The answer should be 14/15.
Step-by-step explanation:
The answer is 14/15 because -2/5 and 4/3 with a common denominator turns into -6/15 and 20/15.
Then you add both of them together.
-6/15 + 20/15 = 14/15

Answer: 4 and 12
Step-by-step explanation:
Let x be the "another number"
Therefore, "one number" is 1/3x
1/3 x + x = 4/3 x
4/3 x = 16
1/3 x = 4
x = 12
Therefore, the numbers are 4 and 12.
Let d = discriminant
d = b^2 - 4ac
Let a = 2, b = 4 and c = -9
We now plug and chug.
d = (4)^2 - 4(2)(-9)
d = 16 - 8(-9)
d = 16 + 72
d = 88
