Set the equation for AB equal to BC and solve for x giving you 16 than pull 16 into X in the AB equation giving you 21 for the measure of AB

Answer:

AB = 21 is the measurement.

Step-by-step explanation:

It is given in the question that B is the mid point of AC.

AB = x + 5 and BC = 2x -11

Since B is the midpoint of AC, therefore AB = BC

x + 5 = 2x - 11

2x - x = 11 + 5 = 16

x = 16

Therefore AB = x + 5 = 16 + 5 = 21

Length of AB is 21.

A talk driver charges $3.50 per mile driver gives a 10mile ride a 5.5 mile ride and a 19 mile ride.he then spends $50 to fill up

salantis [7]

Answer: The driver has $95.25 after the last ride.

Step-by-step explanation: First we need to know how much money he recieved from each ride. Multiply 3.5 with each number.

$3.5 x 10 = $35

$3.5 x 5.5 = $19.25

$3.5 x 19 = $91

Now add them up.

$35 + $19.25 + $91 = $145.25.

However, he spends $50 on gas. So subtract $145.25 and $91.

$145.25 - $91 = $95.25.

Therefore, the driver has $95.25 after the last ride.

Which of the following is not a possible value for a probability?

yan [13]

C, 11/10 is not a possible value for probability, as it is not an actual situation one could be in. For example, if you can get a maximum of ten questions correct on your quiz, and you get eleven correct, that would no make much sense in the real world, unless if you consider extra credit an "extra question."
