16. Construct 3 equations starting with x = 5.
strojnjashka [21]

<em><u>T</u></em><em><u>O</u></em><em><u> </u></em><em><u>F</u></em><em><u>I</u></em><em><u>N</u></em><em><u>D</u></em><em><u>:</u></em><em><u> </u></em> construct 3 equation starting with x=5?

<em><u>S</u></em><em><u>O</u></em><em><u>L</u></em><em><u>U</u></em><em><u>T</u></em><em><u>I</u></em><em><u>O</u></em><em><u>N</u></em><em><u>:</u></em><em><u> </u></em>

The equation is in the form of variable and constant equating.

Let the equation be x=5.

<em><u>T</u></em><em><u>O</u></em><em><u> </u></em><em><u>C</u></em><em><u>R</u></em><em><u>E</u></em><em><u>A</u></em><em><u>T</u></em><em><u>E</u></em><em><u> </u></em><em><u>A</u></em><em><u>N</u></em><em><u> </u></em><em><u>E</u></em><em><u>Q</u></em><em><u>U</u></em><em><u>A</u></em><em><u>T</u></em><em><u>I</u></em><em><u>O</u></em><em><u>N</u></em><em><u>,</u></em>

<em><u>F</u></em><em><u>I</u></em><em><u>R</u></em><em><u>S</u></em><em><u>T</u></em><em><u> </u></em><em><u>W</u></em><em><u>E</u></em><em><u> </u></em><em><u>A</u></em><em><u>D</u></em><em><u>D</u></em><em><u> </u></em><em><u>5</u></em><em><u> </u></em><em><u>B</u></em><em><u>O</u></em><em><u>T</u></em><em><u>H</u></em><em><u> </u></em><em><u>S</u></em><em><u>I</u></em><em><u>D</u></em><em><u>e</u></em><em><u>,</u></em>

x + 5=5+5

=x + 5=10

<em><u>S</u></em><em><u>E</u></em><em><u>C</u></em><em><u>O</u></em><em><u>N</u></em><em><u>D</u></em><em><u> </u></em><em><u>W</u></em><em><u>E</u></em><em><u> </u></em><em><u>S</u></em><em><u>U</u></em><em><u>B</u></em><em><u>R</u></em><em><u>A</u></em><em><u>C</u></em><em><u>T</u></em><em><u> </u></em><em><u>5</u></em><em><u> </u></em><em><u>B</u></em><em><u>O</u></em><em><u>T</u></em><em><u>H</u></em><em><u> </u></em><em><u>S</u></em><em><u>I</u></em><em><u>D</u></em><em><u>E</u></em><em><u>,</u></em>

x — 5=5—5

=x—5=0

<em><u>T</u></em><em><u>H</u></em><em><u>I</u></em><em><u>R</u></em><em><u>D</u></em><em><u> </u></em><em><u>W</u></em><em><u>E</u></em><em><u> </u></em><em><u>M</u></em><em><u>U</u></em><em><u>L</u></em><em><u>T</u></em><em><u>I</u></em><em><u>P</u></em><em><u>L</u></em><em><u>Y</u></em><em><u> </u></em><em><u>5</u></em><em><u> </u></em><em><u>B</u></em><em><u>O</u></em><em><u>T</u></em><em><u>H</u></em><em><u> </u></em><em><u>S</u></em><em><u>I</u></em><em><u>D</u></em><em><u>E</u></em><em><u>,</u></em>

I need help with this question please?! I'm having a hard time answering it!

Maurinko [17]

Answer:

616 square centimeters

Step-by-step explanation:

Area of a circle is equal to pi × r^2. In this case, they have asked that you substitute 3.14 or 22/7 for pi, so I will be using 22/7, instead.

Diameter is equal to 2r; to find the radius, simply divide 28 by two. This gives us a radius of 14.

Multiply 14 squared by 22/7:

(22/7)(14^2)

This gives us (22/7)(196); (4312/7); 616.

Therefore, the area of the circle is approximately 616 square centimeters.
