Answer:
You are supposed to find how much 2 packages of chicken costs when each package is 12.36, 1/2 lb of broccoli when one pound costs 1.98, and 1 gallon of milk with 3.49 per gallon. After that, you need to find how much Susan paid with when she recieved 80 cents in change.
(2*12.36)+(1.98*0.5)+3.49+0.80=x
find out what x is to get the answer.
find y which is 4 (12/3) then in would be a straight line horizontally because y is going to always equal 4. Don't know if this helps but here you go. Have a good day.
If you represent the problem in a diagram, you will form a triangle with 3 known length of the sides. When you are given all sides, and you are asked to find an angle, you can use the cosine law.
b^2 = a^2 + c^2 - 2ac*cosB
1.4^2 = 1.9^2 + 1^2 - 2(1.9*1)(cosB)
B = 45.78°
First ones 40 and I’m not sure bout the second one but through process of elimination either always or never cause nothing in math is uncertain or non existent
