Answer:
here's what we know:
a + b = 72
a - b = 26
We can use the elimination method to solve this problem:
a + b = 72
a - b = 26
---------------
2a = 98
Divide both sides by 2:
a = 49
So we now have:
49 + b = 72
and:
49 - b = 26
Subtract 49 from both sides:
b = 23
and
-b = -23 (multiply both sides by -1) → b = 23
Step-by-step explanation:
Given:
Circumference of a circle = C
Diameter of a circle = d
To find:
The relationship between the circumference, c, and diameter, d, of any circle.
Solution:
We know that, circumference of a circle is

It can be written as

![[\because d=2r]](https://tex.z-dn.net/?f=%5B%5Cbecause%20d%3D2r%5D)
On dividing both sides by d, we get

Therefore, the correct option is (F).
<em>The answer is
</em>The reason we get this answer is because when you are converting from exponential form, to radical form you always place the numerator as our constant's exponent in the radical <em>(

is called the radicand because it is located in the radical)</em> and the denominator in front of the radical, where it would be called the index.
<em>Here's what a formula would look like:</em> ![( \sqrt[n]{x} ) ^{q}=x^{ \frac{p}{q} }](https://tex.z-dn.net/?f=%28%20%5Csqrt%5Bn%5D%7Bx%7D%20%29%20%5E%7Bq%7D%3Dx%5E%7B%20%5Cfrac%7Bp%7D%7Bq%7D%20%7D%20)
