The 1st one
y <x-1 and y>=-2x +4
Answer: c > -25
From the question you can get the equation:
5 - 3c > 80; subtract 5 from both side
-3c > 75; divide -3 from both side
c > -25
So numbers including: -24, -23, -22, -21…
are all numbers that could work
Answer: y=-1/2x+2/3

1:sum of all side of triangle is 180 degree(here is 220)
3: try in copy and u will able to solve
4:first of all make 9 cm as shown in figure and draw 15 . finally measure the remaining side.
5: 3y+5y+y=180
9y=180
hence,y=20
