The difference of three and the reciprocal of a number is equal to the quotient of 20 and the number. find the number.

Equation to find number: - 3 =

Number's value: n =

Step-by-step explanation:

Let n be the unknown number.

The reciprocal basically makes the number (n in this case) a fraction. So, that being said, the reciprocal of n would be .

The difference of three and the reciprocal of a number () would be - 3.

The quotient of 20 and the number (n) would be .

So, with this information we've gathered so far, we can come up with an equation to find what the number equals.

Equation: - 3 =

To find what the number equals we must solve the equation.

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363
