Answer:

No answer as written. 16 if we add an equals sign.

Step-by-step explanation:

As written, there is no "=" sign in either expression. That means they are only expressions, not equations. x can be anything. 10, 12345, 0.00000343345567788, etc. There is nothing that restricts the value of x.

If we set the two expressions equal to each other, we can calculate a value of x:

(2x + 30) = (5x - 18)

3x = 48

x = 16

Not sure how to do this

Answer:2x × 3 (Don't solve it cause you cant)

Step-by-step explanation:For the first one in parentheses you can't do it because their has to be an x with the two so you can do the problem.

For the next one you can do it. So for every letter that doesn't have a number their is always an invisible 1 in front of it. So it's 1x to the second power + 1x-1 so 1×1 is 1. 1x+1x=2x and the 2 and the one that doesn't have a letter equals 3. So the answer is

2x × 3 Hopefully this is correct and helps you out!

horsena [70]

Answer:

7/12 probability of randomly choosing a lunch bag that contains either an apple or banana

Step-by-step explanation:

We have these following probabilities:

1/4 probability that a lunch bag contains an apple.

1/3 probability that a lunch bag contains a banana.

What is the probability of randomly choosing a lunch bag that contains either an apple or banana?

$P = \frac{1}{4} + \frac{1}{3} = \frac{3 + 4}{12} = \frac{7}{12}$

7/12 probability of randomly choosing a lunch bag that contains either an apple or banana
