Answer:x=53/6 and y=-55/6
Step-by-step explanation:
Let the first number x
Second number b y
Sum of the numbers x+y=-1/3
x-y=18
Solve simultaneously
Using elimination method
We get
2y=-55/3
y=-55/6
Substitute for y in equation 1
x+55/6=18
x=18-55/6
x=53/6
Does it say how many of the marbles in the bag are red? Normally you will want to divide the amount of red marbles to the amount total marbles and you will get a percent. It's also note worthy that it states the marble going back into the bag. It would change if it was left out still.

Answer:
b = 8 and b = 8
Step-by-step explanation:
f(b) =b² − 16b + 64 is set equal to zero and solved for b:
f(b) =b² − 16b + 64 = 0
This quadratic can be factored, as follows: f(b) = (b - 8)(b - 8) = (b - 8)² = 0
There are two real, equal zeros: b = 8 and b = 8.
55 add 75 to 50 subtract from 180
