Answer:

Answer:

x = 4

Step-by-step explanation:

9x -5=31

Add 5 to each side

9x-5+5 = 31+5

9x = 36

Divide by 9

9x/9 = 36/9

x = 4

Answer:

First isolate your X by adding the 5 to both sides of the equation

9x -5 + 5=31 + 5

So now the equation is

9x=36

Then you want to get the X completely alone by dividing 9 from both sides

9x/9=36/9

And your answer is

x=4

Which statement is true? A.

|–4| < 4

B.

|–1| < 0

C.

|–6| = –6

D.

|–14| > 10

D. This is because the I I symbols means that it is the same with or without the negative symbol. So, take away the negative. 14 is greater than 10, correct?

I really need help and FAST Describe and correct the error in finding the solution to 8p (>/=) -7 8p (>/=)-7

8p/8 (=) -7/8

p (=) -7/8

8p >/= -7

8p/8 >/= -7/8

p >/= -7/8

The last two equation only has the equal "=" sign. The greater than ">" sign was removed.

Greater than ">" sign should not be removed because the expression is an inequality.

Inequality expressions deal with numerous numbers that can make the inequality true.

Putting only an equal sign will limit the number option into 1. It will only make half of the inequality true. P = -7/8 but it is not > -7/8.

8p/8 >/= -7/8

p >/= -7/8

A class has 18 boys and 14 girls. One student is selected. F is the event of selecting a girl, and K is the event of selecting Kate, one of the girls in the class. Determine P(K | f. and P(F | K).

B.

The Probability of choosing a girl is 17/30.

The probability of choosing an A student is 5/30

The P(girl) + the P(A student) = 17/30 + 5/30 = 22/30 = 11/15.
