A coffee shop sells cups of coffee and breakfast Sandwiches. Roland buys 2 cups of coffee and 2 sandwiches and spends $22. Mariel buys 5 cups of coffee and 3 sandwiches and spends 40. How much does a cup of coffee cost? How much does a sandwich cost?

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
