Answer:
To solve this we need to form 2 equations with only 2 variables.
x+4y-5z=-7
2x+y+5z=8
3x+5y=1
15x+10y+15z=35
6x+3y+15z=24
9x+7y=11
Now we need to use these to find x and y
9x+15y=3
9x+7y=11
8y=-8
y=-1
Therefore:
x=2
From this we can find that:
2(2)-1+5z=8
Therefore z=1
The answer is x=2, y=-1, z=1

Answer: 85.5
Step-by-step explanation:
There are 22 data points in the data set.
We can find the median by looking at the 11th and 12th scores, and averaging them.
The 11th score is 85
The 12th score is 86
The average of the two is 85.5
Hence the answer is 85.5
Answer:
a) en cuántas filas la suma es igual?
2+7+2+0+2=13
0+1+6+1+0=8
2+0+2+8+1=13
es igual en dos filas la primera y la última
b)en cuántas columnas la suma es igual?
2+0+2=4
7+1+0=8
2+6+2=8
0+1+8=9
2+0+1=3
es igual en dos columnas la segunda y la tercera
listo :)
