Answer:
A. 11
Step-by-step explanation:
BC×AC = DC × LC
7(2x +3 +7 ) = 9 ( x+ 1 +9)
7 ( 2x +10) = 9( x + 10 )
14x - 9x = 90 - 70
5x = 20
x = 4
then,
AB = 2x + 3
= 2× 4 + 3
= 11
Using it's concept, it is found that the probabilities are given as follows:
a.1/2, 1/9, 5/9.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, 90 out of 180 individuals are children, hence the probability is given by:
p = 90/180 = 1/2.
Out of 90 adults, 60 - 50 = 10 preferred cheeseburgers, hence the probability is given by:
p = 10/90 = 1/9.
Of the 180 individuals, 90 are children, and 10 are adults who prefer cheeseburgers, hence the probability is given by:
p = 100/180 = 10/18 = 5/9.
Hence option a is correct.

Answer:
-2x-10
Step-by-step explanation:
Distributive Property is basically a term for opening parentheses. So, in your case -2(x+5) we would multiply x and 5 by -2. X times -2 is -2x and 5 times negative 2 is -10. -2x-10 would be your final answer.
