Answer:
The answer to your question is the first graph.
Step-by-step explanation:
It seems that the first graph is correct because the height of the bars is equal to the grade get by the students.
The second graph is incorrect because the height of the bars is different from the grade the students got. Only the bar of Levi is correct.
The third graph is incorrect, just observe the height of John's bar to determine that the graph is wrong.
Also, the last graph is incorrect, in this graph, all the bars are different from the grade the students got.

Answer:
x=-4, y=7
Step-by-step explanation:
-5x-10y=-50...(1)
Multiply both sides by -1:
5x+10y=50
5x=50-10y
x=(50-10y)/5
Substitute <u>x=(50-10y)/5</u> into second given eqaution:
10(50-10y)/5+8y=16
Cancel out common factor 5:
2(50-10y)+8y=16
100-20y+8y=16
-12y=16-100
-12y=-84
y=84/12
y=7
Substitute y=7 into equation (1)
-5x-10(7)=-50
-5x-70=-50
-5x=-50+70
-5x=20
x=-20/5
x=-4
Each piece must be 1/12 of the whole. They must add up to 9/8 of a meter.
(9/8 m) * (1/12) = 9 / 96 m long. But this reduces.
3 / 32 m long is lowest form of the answer
Check
If you multiply 3/32 by 12, you should get back to 9/8
3/32 * 12 = 36/32 = 9/8 which is what we tried to do.
