Can somebody me with this question?

B

Step-by-step explanation:

Solve the first half of the equation-

-8x+3 >/=27

-3 -3

-8x>/=24

divided by -8 on both sides

x</=-3

Now for the second side:

-13x+5>/= 57

-5 -5

-13x>/=52

divide by -13 in both sides

x</=-4

We now have two equations. The answer would be x</=-3 because -4 is also less than three, so it can be simplified down to -3. I know you might not have needed the explanation since it’s just khan academy, but I figured I’d explain it anyway :)

15%

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.

the correct answer is 1: 2
