Answer:

x = 5/2

x = 2 1/2

x = 2.5

Step-by-step explanation:

3x - 1 - (x + 3) = 1

3x - 1 - x - 3 = 1

2x - 1 - 3 = 1

2x - 4 = 1

2x = 1 + 4

2x + 5

2x = 5

x = 5/2 → 2 1/2 → 2.5 ( can be written in any of these forms depending on what you need to do)

<em>Hope this helped! :)</em>

Answer:

<h2>x = 5/2</h2>

Step-by-step explanation:

3x−1−(x+3)=1

<u>First remove the bracket</u>

That's

3x - 1 - x - 3 = 1

<u>Group the constants at the right side of the equation</u>

That's

3x - x = 1 + 1 + 3

Simplify

We have

2x = 5

Divide both sides by 2

That's

2x / 2 = 5/2

<h3>x = 5/2</h3>

Hope this helps you

How many combinations of 7 candidates can fill 3 vacancies on a city council?
yKpoI14uk [10]

Answer:

35 combinations

Step-by-step explanation:

You have to use the formula for finding combinations in probability.  It looks like this:

₇C₃ = \frac{7!}{3!(7-3)!}

so that gives you

₇C₃ = \frac{7*6*5*4!}{3*2*1*4!}

The 4 factorials cancel each other out, and when you do the math, you get 210/6.  That divides evenly into 35.  So there are 35 combinations.
