A. x -13= x+1 (NO SOLUTION)

B. x + 1/2= x - 1/2 (NO SOLUTION)

C. 2(x + 3)=5x + 6 - 3x (TRUE)

D. x - 3 = 2x - 3 - x (TRUE)

E. 3(x - 5) = 2( x - 5) + 2 (TRUE)

I'm no sure what Im supposed to be doing-

But if I'm supposed to determine if true well there you have it

Find the probability for choosing a letter at random from the word: Probability P(not P) A.) 1/11 B.) 2/11 C.) 5/11 D.) 10/11

elixir [45]

Answer:

D.) 10/11

Step-by-step explanation:

Here the given word Probability has 11 letters in it. And we have to calculate the Probability of not selecting a letter P from the above word.

So the formula for calculating any probability is Total Favorable outcomes / Total number of outcomes.

Here total number of outcomes are 11 as word Probability has 11 letters.

So the probability of selecting letter P from word Probability = $\frac{1}{11}$

Now the P(not P) = 1 - P(selecting letter P)

= 1 - $\frac{1}{11}$ = $\frac{10}{11}$

Turn this into a equation the sum of twice r and three timea s is identical to thirteen

Goryan [66]

In equation form it would be the following:

2r + 3s = 13.

I believe.
