Experimental Probability is the number of times an event occurs over the total number of times the activity is preformed. Does that help or make sense?\
Answer:
0
Step-by-step explanation:
Isolate the variable x. First, distribute 3 to all terms within the parenthesis.
3(2x + 3) = 3(2x) + 3(3) = 6x + 9
6x + 9 = 9
Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. First, subtract 9 from both sides.
6x + 9 (-9) = 9 (-9)
6x = 0
Divide 6 from both sides.
(6x)/6 = (0)/6
x = 0
0 is your answer.

Answer:
18 cellphones
Step-by-step explanation:
75 x 6= 450
3 x 6= 18
J/6 = 9/10 is the proportion that we are trying to solve. Let's use cross products, or multiplying the numerator of one fraction by the denominator of the other fraction, and setting these two numbers equal to one another in an equation.
9 (6) = 10 (j)
When we combine like terms (multiply), we get
54=10j
We need to divide both sides by 10, to get the variable alone.
j = 5.4
I'm assuming that the capital and lower case x's are the same
You need to get x by itself
Add 2 to each side
⇒
Add like variables together
