Answer:
LEAST DIFFICULT: B
MOST DIFFICULT: I
Step-by-step explanation:
LEAST DIFFICULT:
The easiest systems of equations to solve are ones in which x or y is equal to just a number , because in this case, you can just sub in that number in the other equations. Though not the only one, B is an example of this.
MOST DIFFICULT:
More difficult systems of equations to solve are the ones with different amounts of x and y as it requires more computation. Set I is an example of this
There are 1 rectangle and 2 triangles.
The area of the rectangle is 5 x 7 =35
The are of the triangle is 7 x 2 = 14(1/2) = 7
There are 2 triangles, so 7 x 2 = 14
14 + 35 = 49
49 is your answer
hope this helps
