It depends on how many sided die it is

One die has a 5.
The only way to get a sum of 7 is by rolling a 2 on the other die.
The other die has 6 equally likely outcomes, the numbers 1, 2, 3, 4, 5, or 6.
The probability of rolling a 2 with one die is 1/6.

The answer is 1/6.

What to do if quadratic equation has a negative spuare root?
alex41 [277]

If the negative square root is found to be one of your solutions, then that is indicative of a pair of imaginary roots (the imaginary i). According to the conjugate rule, if you have one solution that is imaginary, you will have another but with the opposite sign. For example, if a solution to a quadratic is found to be 2 - i, then its conjugate, 2 + i is also a solution. They will ALWAYS go in pairs. Same thing with radical solutions. If one solution is found to be 3+\sqrt{5}

then 3-\sqrt{5} will also be a solution.

A rental car company is running two specials. Customers can pay $40 to rent a compact car for the first day plus $2 for each add
svp [43]

Answer: 5

Step-by-step explanation:

The equation to solve this problem is 40 + 2x = 25 + 5x

Now, to solve for x you first need to subtract 25 from each side:

15 + 2x = 5x

Next, subtract 2x from each side:

15 = 3x

Finally, divide both sides by 3:

5 = x
