I WILL NAME BRAINLIEST (: 20 points (: Sorry you can't see it well, but it says: " Ian's mom sang him S songs. His sister sang him two times as many songs as his mom had. If Ian listened to nine songs in all, how many did his mom sing? Write an equation and solve.

3

Step-by-step explanation:

Lan's mom sang S song and his sister sang twice as many as the songs the mom sang. We can conclude that the sister sang 2S songs.

The total number of songs is 9.

Here is the equation:

● S + 2S = 9

● 3S = 9

Divide both sides by 3:

● 3S/3 = 9/3

● S = 3

Then the mom sang 3 songs

do you have any choices

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.
