Let's simplify step-by-step.
2(a−3)+4b−2(a−b−3)+5
Distribute:
=(2)(a)+(2)(−3)+4b+(−2)(a)+(−2)(−b)+(−2)(−3)+5
=2a+−6+4b+−2a+2b+6+5
Combine Like Terms:
=2a+−6+4b+−2a+2b+6+5
=(2a+−2a)+(4b+2b)+(−6+6+5)
=6b+5
Answer : =6b+5

You weigh six packages and find the weights to be 20, 12, 52, 16, 48, and 44 ounces. If you include a package that weighs 60 oun

Answer:

median

Step-by-step explanation:

The first step is to sort the numbers from largest to smallest (you could go the other way as well).

60 52 48 44 20 16 12

The median is the middle number 44 in this case. The median has 3 numbers on its left and 3 on its right (in this case). 44 has 60 52 48 or its left and 20 16 and 12 on its right.

The mean is the average. We'll call it the new average

The mean is 60 + 52 + 48 + 44 + 20 + 16 + 12 = 252

The new mean is 252 / 7 = 36

=====================

The old median is the average between the middle 2 numbers (before you added 60 you had 6 numbers)

52 + 48 + 44 + 20 + 16 + 12 = the average of 44 + 20 which 64/2 = 32

The old mean was (52 + 48 + 44 + 20 + 16 + 12)/6 = 32.

=======================

The median increased from 44 to 32 = 12

The mean went from 32 to 36 which is 4

Answer: the median increased more

Carla is going to arrange her 4 books on a shelf: Algebra, Trigonometry, Geometry and Calculus. How many different possible arra

PilotLPTM [1.2K]

Arranging of books is an illustration of permutation and combination

There are 24 different possible arrangements she can make

<h3>How to calculate the number of arrangement</h3>

The number of books is given as:

n = 4

Take the factorial of both sides

n! = 4!

Evaluate

n! = 4 * 3 * 2 * 1

n! = 24

Hence, there are 24 different possible arrangements she can make

A transformation named T maps triangle XYZ to triangle X'Y'Z'. The transformation is a(n) _____.

wel

Answer:

The transformation is called Translation.

Step-by-step explanation:

We have different types of transformation:

Translation: A translation or slide is an isometry in which all points of a figure move the same distance and in the same direction.

Reflection: A reflection is an isometry in which the preimage and the image have opposite orientations. In other words, the image appears backwards.

Rotation: A rotation is an isometry in which a figure has been rotated or turned around a point called center of rotation.

Dilation: A dilation could be an enlargement or a reduction.

In Geometry, "Translation" simply means Moving without rotating, resizing or anything else, just moving.

To Translate a shape: Every point of the shape must move;

the same distance

in the same direction.

So, in this question XYZ translate to $X^{'} Y^{'} Z^{'}$ since every point move in the same distance and same direction.
