Anais bought 3 1/2 yards of ribbon. she had 2 feet 10 inches of ribbon left after trimming some curtains. how many inches of ribbon did anais use to trim the curtains? anais used inches of ribbon.

Anais used 92 inches of ribbon.

Step-by-step explanation:

Anais bought ribbon, the length of the ribbon = yards

1 yard = 36 inches

3.5 yard = 126 inches

She had 2 feet 10 inches of ribbon left after trimming some curtains.

1 feet = 12 inches

2 feet  = 12 × 2 = 24 inches + 10 inches = 34 inches

Therefore, Anais had left 34 inches.

She used ribbons  =  126 - 34 = 92 inches

Anais used 92 inches of ribbon.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

the first one, all those points on the line just make a strait line.
