Marita is cutting rolls of ribbon that are 3 feet long into 1/2- foot pieces. she needs fifteen 1/2- foot pieces for a project. she has 3 rolls of ribbon. does she have enough to cut 15 pieces? explain.

Yes

Step-by-step explanation:

3 * 2 = 6. So you can get 6 1/2 foot pieces out of 1 roll. She has 3 rolls. 6 * 3 = 18. 18 is more than 15.

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
