The sum of 3 times a number and 9 equals 4 use the variable b for the unknown number write in an equation

b= -5 over 3

Step-by-step explanation:

create the equation 3b + 9 = 4

subtract 9 from each side to isolate the variable

we are left with 3b = -5

to further isolate the variable divide by 3

3b/3 = -5/3

3b divided by 3 is b, which is equal to -5 divided by 3; -5/3

b = -5/3 is your answer

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.

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.
