In physical education class, Ariel shoots free throws and lay-ups. She earns 1 point for each free throw she makes and 2 points for each lay-up she makes. The greatest number of points that she can earn is 30. She has to make at least 15 free throws and lay-ups altogether. One of the inequalities would be 1x + 2y < 30 where x represents the number of free throws made and y represents the number of lay-ups made. Write the other inequality for the system of inequalities that describes the constraints.

what do u need to know

step-by-step explanation:

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

your answer is -9

step-by-step explanation:

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.
