x = or as a decimal 10.22

Step-by-step explanation:

Step 1 - Put them both into an equation in which it totals 90:

2x - 6 + 7x + 4 = 90

Step 2 - Add the like variables together:

2x + 7x -6 + 4

9x -2 = 90

Step 3 - Add two to each side:

9x -2 + 2 = 90 + 2

9x = 92

Step 4 - Divide both sides by 9 to find x:

x = or as a decimal 10.22

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.
