Answer:

Step-by-step explanation:

Let the number of cows = x

Let the number of chickens = y

4x + 2y = 140

x + y = 54

Multiply the second equation by 2

2x + 2y = 108

Now write the new equation under the first equation and subtract.

4x + 2y = 140

<u>2x + 2y = 108</u>      Subtract

2x = 32                Divide by 2

x = 32/2

x = 16

There are 16 cows and 38 chickens.

Check

16 * 4  =   64

38 * 2 =  <u> 76</u>

Total      140

There are 38 chickens and 16 cows.
38 times 2 equals 76 and 16 times 4 equals 64. 64 plus 76 equals 140.

HELP PLEASE! Square T was translated by the rule (x + 2, y + 2) and then dilated from the origin by a scale factor of 3 to creat
Sveta_85 [38]

The statement that explains why the squares are similar is

Option C. Translations and dilations preserve betweenness of points; therefore, the corresponding sides of squares T and T″ are proportional.

<h3>Further explanation</h3>

<em>There are several types of transformations:</em>

  1. <em>Translation</em>
  2. <em>Reflection</em>
  3. <em>Rotation</em>
  4. <em>Dilation</em>

Let us now tackle the problem!

\texttt{ }

This problem is about Translation and Dilation.

<em>Properties of </em><em>Translation</em><em> of the images compared to pre-images:</em>

  • preserve Side Length
  • preserve Orientation
  • preserve Collinearity
  • preserve Betweenness of Points

\texttt{ }

<em>Properties of </em><em>Dilation</em><em> of the images compared to pre-images:</em>

  • not preserve Side Length
  • not preserve Orientation
  • preserve Collinearity
  • preserve Betweenness of Points

\texttt{ }

From the information above, we can conclude that:

Option A is not true because Dilations do not preserve side length.

Option B is not true because Dilations do not preserve orientation.

Option C is true because Translations and Dilations preserve betweenness of points.

Option D is not true. Although Translation and Dilations preserve collinearity but it cannot be related to the corresponding angles are congruent.
