Answer:

x = 12

Step-by-step explanation:

Angle 1 = 8x - 17

Angle 2 = 5x + 19

These are congruent which means they are the same so the equation is:

8x - 17 = 5x + 19

3x - 17 = 19

3x = 36

x = 12

Answer:

last option is correct

Step-by-step explanation:

8x-17=5x+19(being corresponding angles)

8x-5x=19+17

3x=36

x=36/3

x=12

Which of the following iſ the best statement of the use of the addition rule of probability?
otez555 [7]

Answer:

Option C

Step-by-step explanation:

Addition theory of probability is used to determine the probability for union of two or more sets.

P(AUB) = P(A)+P(B)-P(AB) is the addition theory of probability for two sets A and B.

P(AUBUC) = P(A)+P(B)+P(C)-P(AB)-P(BC)-P(CA)

for 3 sets

This can be extended to any number of sets

So addition theory has nothing to do with independent events both occurring

Option c is the right answer.

4. Lucy is k years old. She has a sister who is three years younger than she is and
WITCHER [35]

Answer:

4k - 8

Step-by-step explanation:

Lucy is k years old so we know k is an important part of this problem.
Sister 1 is 3 years younger, so she is k - 3 years old.
Sister 2 is 5 years less than twice Lucy's age therefore, she is 2k (twice Lucy's age) - 5 years old.
Now we have: k + (k - 3) + (2k - 5)
We can simplify like terms with the k's and get 4k. then we add (-3) and (-5) to get 4k - 8.

Hope this helps!
