the length of a rectangular building is 6 feet less than 3 times t he width. The perimeter is 120 feet. Find the width and the length of the building.

Answers

Answer 1

Answer: Call the width x. Note that the length is 3x-6. We know that double the width plus double the length is 120, so we write an equation:

$2(x)+2(3x-6)=120$
$2x+6x-12=120$
$8x-12=120$
$8x=132$
$x=16.5$
If x is 16.5, the width is 16.5, and the length is $3 \cdot 16.5 - 6 = 43.5$ .

Answer:

Step-by-step explanation:

Because side BD is similar to side BA

triangle BCD seems to be double the size of triangle BAD

By finding the side lengths of the missing sides BC and CD you can get the perimeter.

Because we know the triangle is double the size you can double the lengths of AD and BD to get 24 and 18, if you add 6,9,24, and 18. You will get 57.

Sales for a business were 3 million dollars more the second year than the first, and sales for the third year were double the sales for the second year. If sales for the third year were 38 million dollars, what were sales, in millions of dollars, for the first year?A. 16
B. 17.5
C. 20.5
D. 22
E. 35

Answers

The sales in million of dollar, for the first year is 16 million in dollars.

What are sales ?

"In general business operations, sales refer to any transactions where money or value is exchanged for the ownership of a good or entitlement to a service."

Given,

The sales for the third year is 38 million dollars.

Let the sales for the first year be x

and the sales for the second year be y

So, x+3 = y;

Sales for the third year = $\ 2(x+3)$
