Answer:

x = 9

Step-by-step explanation:

The angles in red are equivalent and the triangle is isosceles.

This means the sides with lengths 12 and x + 3 are equivalent.

x + 3 = 12

x + 3 - 3 = 12 - 3

x = 9

7. A coin is tossed and a day of the week is selected. What is the probability that you get tails and a day that begins with "S"

Mrrafil [7]

Answer:

1/7

Step-by-step explanation:

Lets start with the probability of flipping tails, 1/2.

Then the probability of the day starting with the letter s, 2/7.

Calculate the final probability by multiplying the two together.

$\frac{1}{2}*\frac{2}{7}=\frac{2}{14}$

You can simplify 2/14 down to 1/7
