Farah found 7 rolls of teal ribbon and blue ribbon. Each roll of teal ribbon was 1 meter long and each roll of blue ribbon was 7 meters long. If Farah found 37 meters of ribbon in total, how many rolls of each color did she find?

Is she found 7 rolls of 1 meter is 7 meters in total and she found 37 meter in total so 37-7 it’s 30 and 30 divided by 5 equals 7 so the answer is 5 rooms

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
