You have $100 to spend on a bbq where you want to serve chicken and steak. chicken costs $1.29 per pound and steak costs $3.49 per pound. write the function that relates the amount of chicken and steak you are able to buy.

3.49s+1.29c=100
C is standing for chicken while s is standing for steak. Since the values are per pound, you just have to multiply it. Finally, all you have is 100 so you have a limit.

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
