y = x + 2 \\ x + y = 8 \\ x + x + 2 = 8 \\ 2x = 8 - 2 = 6 \\ 2x = 6 \\ x = 6 \div 2 = 3 \\ y = x + 2 = 3+ 2 = 5

Answer

X= 3 y=5

Step-by-step explanation:

y=x+2

x+y=8

plug in (x+2) for y into the equation x+y=8 to get the same variable.

x+(x+2)=8

2x+2=8

2x=6

x=3

plug in x=3 into x+y=8

3+y=8

y=5

Therefore, x=3, y=5

The dot plot shows the number of pencils each boy has at his desk in class.
Elanso [62]

Answer:

The median is 2

Step-by-step explanation:

Here, we want to get the median for the number of pencils

Firstly, we have to write out the numbers that form the box plot ; we have this as;

1,1,1,2,2,2,2,3,3,5

the median is sum of the 5th and 6th term divided by 2

The 5th term is 2

The 6th term is 2

So the median is;

(2 + 2)/2

= 4/2 = 2
