Lydia gas tank was 3/4 full when she left on a trip. She used 8 gallons of gasoline during her trip. Now, 5.5 gallons of gasoline remain in the gas tank. How many gallons of gasoline dose the tank of Lydia's car hold? Show your work.

The tank holds 18 gallons of gasoline.

Step-by-step explanation:

Let x represent the number number of gallons of gasoline that the tank of Lydia's car hold.

Lydia gas tank was 3/4 full when she left on a trip. It means that the amount of gasoline in the tank was 3x/4 gallons.

She used 8 gallons of gasoline during her trip. The amount that would be left is

3x/4 - 8

Now, 5.5 gallons of gasoline remain in the gas tank. It means that

3x/4 - 8 = 5.5

Multiplying both sides of the equation by 4, it becomes

3x - 32 = 22

3x = 22 + 32

3x = 54

x = 54/3

x = 18

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

answer: 88
