Six less than a number is less than the quotient of the number and three

Answers

The expression that represent six less than a number is less than the quotient of the number and three is given as x - 6 = (x-6)/3

Word problem and equation

The statement Six less than a number is x - 6 where x is the unknown number.

The quotient of the number and three is expressed as (x-6)/3

Equate the expressions

x - 6 = (x-6)/3

Hence the expression that represent six less than a number is less than the quotient of the number and three is given as x - 6 = (x-6)/3

jerry receives a 15% employee discount at the store where he works. if he pays $219.30 for an item, what was the original price of the item?

Answers

Given:
Employee discount 15%.
Amount paid by employee - $219.30

If the discount is 15%, then the amount paid by the employee is only 85% of the original price. Therefore, to get the original price, we do this computation.

Original price = amount paid by employee ÷ (100%-employee discount)

O.P = $219.30 ÷ (100% - 15%)
O.P = $219.30 ÷ 85%
Original Price = $258

Discount : $258 * 15% = $38.70

Amount paid by employee : $258 - 38.70 = 219.30

Here's the math to solve it:
Original price = $219.30 ÷ (100% - 15%)
Original price = $219.30 ÷ 85%
Original Price = $258

Discount: $258 x 15% = $38.70

Amount paid by employee: $258 - 38.70 = 219.30

According to astronomers, what is a "light year"

Answers

A light year is the distance light travels in one year.

Let's figure out what this distance is shall we...?

We know that speed = distance / time, therefore distance = speed x time.

Speed of light = 299,792,458 m/s

Time (One year) = 31,536,000 s

That is a ridiculous:

9.454254955 x 10¹⁵ metres,

Which is approximately:

9,400 trillion metres.

Only "one light year" away... That's a hell of a distance.

Here's a hint : A light year is a distance, not a time.

A light year is a unit of length used informally to express astronomical distances.
