Answer:

x=t-7

Step-by-step explanation:

To make x the subject of the formula 7 + x = t

<em>What</em><em> </em><em>we</em><em> </em><em>mean</em><em> </em><em>is</em><em> </em><em>that </em><em>we</em><em> </em><em>want</em><em> </em><em>x</em><em> </em><em>to</em><em> </em><em>stand</em><em> </em><em>alone</em><em>.</em>

<em>So</em><em> </em><em>if</em><em> </em><em>we</em><em> </em><em>want </em><em>x</em><em> </em><em>to </em><em>stand</em><em> </em><em>alone</em><em> </em><em>then</em><em> </em><em>we </em><em>will</em><em> </em><em>subtract</em><em> </em><em>both</em><em> </em><em>sides </em><em>by</em><em> </em><em>7</em><em> </em><em>to</em><em> </em><em>make </em><em>the</em><em> </em><em>x</em><em> </em><em>stand</em><em> </em><em>alone</em><em>.</em>

-7+7+x=t-7

x = t - 7

So now the final answer becomes;

<em>x</em><em> </em><em>=</em><em> </em><em>t</em><em> </em><em>-</em><em> </em><em>7</em>

Ksivusya [100]
E=\frac{|x-x_r|}{x_r}\times100

where x is the estimated value and xr the real value

\begin{gathered} E=\frac{|50-56|}{56}\times100 \\  \\ E=\frac{|-6|}{56}\times100 \\ E=\frac{6}{56}\times100 \\ E=10.71 \end{gathered}

Ari is designing a patio that will be 20 feet long and 16 feet wide. He makes a scale drawing of the patio using a scale of 1 in
Anna007 [38]

Answer:

80 square feet

Step-by-step explanation:

This time I will get it right for sure!

So first we need to find the area in feet, and then convert it in to inches.

1) Since the patio has the shape of a rectangle, then the formula is:

A = a * b

A = 20 * 16

A = 320 feet

2). Now we have to find the ratio, so:

320 / 4 = 80

So, the answer is

1 square inch to 80 square feet.

Hope this helps))
