Alexandra and Chi compete in an Olympic-type triathlon consisting of a 1.5 km swim, a 40 km bicycle ride, and a 10 km run. there are two transitions in the race were the participants take time to change from one mode of the race to another. their times from the race are shown below. how long does it take alexandra to complete the triathlon? write and solve a linear equation to model the total time. how long does it take chi to complete the triathlon if she also gets a flat tire that takes 10 minutes t fix? write and solve a linear equation to model the total time. who won the race? how did chi's flat tire affect the outcome? would the outcome have been different if it took 20 minutes for chi to fix the flat tire? exlpain HELP NEED IT ASAP1

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

step-by-step explanation:

im not sure what the answer is

answer:   x*94 +688*6   = 267*100

94x+4128=26700    

94x=22572     /94

x=240.128
