Write Systems of Linear Equations:Question 3 A school has 5,826 students. There are 1,398 less male students than female students. Let x represent the number of male students and let y represent the number of female students. Which system of equations represents this situation? Select one A-X+y=5 826
x=y-1.398 O
B-x+y=5 826
y=x-1.398 O
C-X+y=5 826
y=1 398x
D-x+y=5,826
x=1.398y

A

Step-by-step explanation:

Since x is male and y is female, and the student population adds up to 5826, we can assume that:

x+y=5826

Since there are 1398 less male students than femailes, we come up with this:

x=y-1398, or y=1398+x

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.
