Their sum is − 1/3 and their difference is 18

Rina8888 [55]

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

4 to the 3rd power X blank =1 what is the blank?

BaLLatris [955]

If you mean this: $4^{3x} = 1$ then x = 0. The property in play here is the following: Any number raised to the "0" power is equal to "1". In this case, we would need to set the exponent of 3x = 0 and solve for x...

If you mean the equation: $4^{3} x = 1$ then to solve for x(your blank), simply divide both sides of the equation by $4^{3}$ :

You would have x = $\frac{1}{4^3}$ this can also be written as $4^{-3}$
