An algebra i test contains 40 questions. some of the questions are worth 4 points each, and some are worth 2 points each. the total test is worth 100 points. let f represent the number of questions worth 4 points and t, the number of questions worth 2 points. solve the system by elimination to find the number of four-point questions on the test.

20 four point and 20 2 point.

Step-by-step explanation:

20x4=80

20x2=20

80+20=100

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
