2x - x + 3x + 5 = 25<br>Solve for X

postnew [5]

Answer:

$\bf x=5$

Step-by-step explanation:

$\bf 2x - x + 3x + 5 = 25$

Combine like terms.

$\bf 4x+5=25$

Subtract 5 from both sides.

$\bf 4x+5-5=25-5$

$\bf 4x=20$

Divide both sides by 4.

$\bf \cfrac{4x}{4}=\cfrac{20}{4}$

$\bf x=5$

What is the median for the following scores for Mrs. Johnson's first test? 59, 22, 87, 44, 96, 38, 70, 85, 79

katrin2010 [14]

To work out the median, you need to numerically sort the data (because currently, it's unordered).

The ordered set of data is: 22, 38, 44, 59, 70, 79, 85, 87, 96

Now you just need to pick the middle value, which is 70:

(as you can see: 22, 38, 44, 59, 70, 79, 85, 87, 96)

Therefore, your answer is 70 :)

<h2>Answer:</h2>

Using the distributive property, we can simplify the expression.

4 × 3 = 12

4 × $\frac{1}{4}$ = 1

4 × $(-\frac{1}{2})$ = -2

Here is the simplified expression:

$12 + c - 2d$
