Answer:

Step-by-step explanation:

2x + -1y = -42

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'y' to each side of the equation.

2x + -1y + y = -42 + y

Combine like terms: -1y + y = 0

2x + 0 = -42 + y

2x = -42 + y

Divide each side by '2'.

x = -21 + 0.5y

Simplifying

x = -21 + 0.5y

A container contains tiles numbered from 1 through 40. A tile is drawn randomly and replaced. Then a second tile is drawn random

amid [387]

Answer:

The correct answer is $\frac{1}{1600}$ .

Step-by-step explanation:

A container contains tiles numbered from 1 through 40.

Let the experiment be to drawn a tile randomly from the container. The draws are carried on by replacement method. Then a second tile is drawn randomly.

Probability that the first tile is number 7 = $\frac{Possible outcomes}{Total outcomes}$ = $\frac{1}{40}$

Probability that the second tile is number 25= $\frac{Possible outcomes}{Total outcomes}$ = $\frac{1}{40}$

Thus the probability of the first tile is number 7 and the second tile is number 25 is given by $\frac{1}{1600}$ .
