7 0

Step-by-step explanation:

<em>1</em><em>.</em><em> </em><em>x</em><em>+</em><em>6</em><em>=</em><em>93</em>

<em>x</em><em>=</em><em>93</em><em>-</em><em>6</em>

<em>x</em><em>=</em><em>87</em>

<em>2</em><em>.</em><em> </em><em>4x</em><em> </em><em>+</em><em>15</em><em> </em><em>=</em><em>29</em>

<em>4x</em><em> </em><em>=</em><em>29-15</em>

<em>4x</em><em>=</em><em>14</em>

<em>x</em><em>=</em><em>14</em><em>/</em><em>4</em>

<em>x</em><em>=</em><em>3</em><em>.</em><em>5</em>

<em>3</em><em>.</em><em> </em><em>x</em><em>+</em><em>9</em><em> </em><em>=</em><em>53</em>

<em>x</em><em>=</em><em>53</em><em>-</em><em>9</em>

<em>x</em><em>=</em><em>44</em>

<em>4</em><em>.</em><em> </em><em>2</em><em>(</em><em>x</em><em>+</em><em>5</em><em>)</em><em>=</em><em>18</em>

<em>2x</em><em>+</em><em>10</em><em> </em><em>=</em><em>18</em>

<em>2x</em><em>=</em><em>18-10</em>

<em>2x</em><em>=</em><em>8</em>

<em>x</em><em>=</em><em>8</em><em>/</em><em>2</em>

<em>x</em><em>=</em><em>4</em>

mariarad [96]

Answer:

9

Step-by-step explanation:

Given that:

Dimension of Original photo = 4 inches by 6 inches

Intended dimension of model = 3 feet by 4 1/2 feets

Converting from feets to inches :

1 foot = 12 inches

Therefore,

Intended dimension of model :

3 feets = (3 * 12) = 36 inches

by 4 1/2 feets = (4 1/2 * 12) = 54 inches

Hence, scale factor required :

36 /4 = 9

54 / 6 = 9

Scake factor = 9
