Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.
Paul and Farid started out at their houses and are biking towards each other. Paul started out
first, and has already gone 2 miles. He bikes at a constant speed of 2 miles per hour. Farid
just left, and rides at 4 miles per hour. When the boys meet halfway between their houses,
they will continue to the park together. How long will that take? How far will each boy have
ridden?
In
hours, both boys will have ridden
miles.

x = 23.78

step-by-step explanation:

9x

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.
