6x+8=-3x-10
9x=-18
x=-2
-3(-2)-10=-4
So x=-2 and y=-4

Answer:
75.36mm
Step-by-step explanation:
Answer:
Clusters at 1 - 2 1/2 and 3 1/2 - 4
Gaps at 1/2 and 3
Spread from 0 - 4
Peak at 4
Graph is not symmetrical.
Explanation:
The clusters are where the data is grouped <em>without </em>gaps. So from 1 - 2 1/2 and 3 1/2 to 4. There are no gaps. Gaps are spaces <em>without</em> data. These spaces have to be within the spread of the data. The spaces without data within the spread are 1/2 and 3. The spread is the smallest data point to the largest one. The peak is the data point with the most dots. The place with the most dots is 4. A symmetrical graph has a center point that everything revolves around and everything is the same on both sides. There is no symmetry in this graph.
let English marks =E
Maths marks = M
Science marks =S
E+M=175 ................(1)
E+S=164...................(2)
E=M+11.......................(3)
PLUGGING VALUE OF "E" IN EQUATION (2) FROM (3)
M+11 +S=164
S=153-M............(4)
PLUGGING VALUE OF "E" IN EQUATION (1) FROM (3)
M+11+M=175
2M=164
M=82
PLUGGING THIS VALUE OF 'M' IN EQUATION (4)
S=153-82
S=71
SCORE OF SCIENCE IS 71
