Find a number you can multiply by the bottom of the fraction to make it 10, 100, or 1000 and multiple both top and bottom by that number then write down just the top number putting the decimal point in the correct spot.

Catarina and Tom want to buy a rug for a room that is 9 by 19 feet. They want to leave an even strip of flooring uncovered aroun
oksano4ka [1.4K]

Answer:

17ft wide

Step-by-step explanation:

The room is 9 by 19ft

Length (x) = 19ft

Width(y) = 9ft

Area of the rug = 119ft^2

x*y = 119 ...........(1)

For the second equation we will make sure the strip around the room is uniform in size

9 - x = 19 - y

-x = 19 - 9 -y

-x = 10 - y

x = y - 10 ..........(2)

Put the value x in equation 1

(y - 10)y = 119

y^2 - 10y = 119

y^2 - 10y - 119 = 0

a = 1, b = -10, c= -119

Use quadratic formula to solve the equation

y = (-b +/-√b^2 -4ac) / 2a

y = [-(-10) +/- √ (-10)^2 - 4(1)(-119)] /2(1)

y = (10 +/- √100 + 476) /2

y = (10+/-√ 576 ) / 2

y = (10 +/- 24) / 2

y = (10 + 24) /2 or (10 - 24)/2

y = 34/2 or -14/2

y = 17 or -7

y = 17 ft

Recall that x = y - 10

x = 17 - 10

x = 7ft
