drek231 [11]

Answer:

The answer is "Option C"

Step-by-step explanation:

The choices were missing in the question, which is defined in the attached file please find it.

To attend university, Chole should pay the cost of a room and board each semester.  Even though the Chole will not be in college, she will still have a room as well as a board and continue living.

Enter the value of b when the expression 9x + b is equivalent to<br> 3(3x + 1).<br> BE<br> ker notes
qwelly [4]

Answer:

b = 3

Step-by-step explanation:

Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other:

First, distribute 3 to all terms within the parenthesis:

3(3x + 1) =

3 * 3x = 9x

3 * 1 =  3

9x + b = 9x + 3

Isolate the variable, b. Subtract 9x from both sides:

9x (-9x) + b = 9x (-9x) + 3

b = 3

3 is your value for b.
