Solve. 2 (x - 1/2) = 3 (5 - 2x) show the steps in your solution.
viktelen [127]

Question 1.). Solve:

2 (x - 1 / 2) = 3 (5 - 2x)

Simplify both sides of equation:

2( x - 1 / 2 ) = 3(5 - 2x )

(2) (x) + (2) ( -1 / 2 ) = (3) (5) + (3) ( -2x )


Distribute:

2x + - 1 = 15 + -6x

2x - 1 = -6x + 15


Add 6x to both sides:

2x - 1 + 6x = -6x + 15 + 6x

8x - 1 = 15


Add 1 to both sides:

8x - 1 + 1 = 15 + 1

8x = 16


Divide both sides by 8:

8x / 8 = 16 / 8

Answer: 2 (x - 1 / 2) = 3 (5 - 2x) ==========> x = 2

Can two box plots have the same range and iqr
Salsk061 [2.6K]
Yes they can!  Just because two plots have the same IQR and range, does not mean that the rest of the data has to be the exact same.  For example, the median.

Find the area.<br> help pls
lions [1.4K]

Answer:

81.6 inches squared

Step-by-step explanation:

The formula for calculating all parallelograms is Area+=base*height.

The height is given to you, 6.8, the base of the figure is also given, 12.

Now all you have to do is to multiply.

That would get you to 81.6.

(When asked for area of parallelogram, the length of any line other than the height and base is not needed)

hoped this helped!
