Math 7a using number sense to solve equations
Anika [276]
Simple...

you have: \frac{n}{3} =12


and

\frac{n}{3} =-12

To solve for....\frac{n}{3} =12

Multiply to remove the denominator-->>

3*  \frac{n}{3} =12*3

n=12*3

n=36

Then-->>>

\frac{n}{3} =-12

Do the same thing-->>

3* \frac{n}{3} =-12*3

n=-12*3

n=-36

Thus, your answer.

1. A Babylonian tablet found in 1936 shows that the Babylonians sometimes used a more accurate value of π than 3. They determine
madreJ [45]

Answer:

<h2>1/4</h2>

Step-by-step explanation:

Area of a circle is given as πr² and its circumference is expressed as 2πr.

If the babylonians determined the area of a circle by taking it as equal to the square of the circle’s circumference then;

Area of circle = (circumference of a circle)²

πr² = (2πr)²

πr² = 4π²r²

Dividing both sides of the equation by πr² we have;

\frac{\pi r^{2}  }{\pi r^{2}  } =\frac{4\pi^{2}  r^{2}  }{\pi r^{2}  }\\1 = 4\pi \\\pi =\frac{1}{4}

The value of π this yields is 1/4
