Answer:

7 inches

Step-by-step explanation:

First you have to find the average height of each class.

4th Grade:

56, 47, 54, 51, 53, 58, 48, 54, 46, 53

Then you have add it all up and divide it by how many students there are.

56 + 47 + 54 + 51 + 53 + 58 + 48 + 54 + 46 + 53 = 520

520 ➗10= 52

Same process for the 7th Grade.

You end up getting 52 and 59. You then Subtract it to get the answer to the question.

52 - 59= 7 inches

Solve the system using substitution.

Alexeev081 [22]

Answer:

Option B that is (2,6) is correct

Explanation:

We have been given with system of equations

$X+Y=8$ and $Y=3X$

Here, we will substitute the value of $Y=3X$ in $X+Y=8$

We will get $X+3X=8$

Further simplification we will get to $4X=8$

Hence, the value of $X=2$

And now, substituting the value $X=2$ in $Y=3X$ we will get $Y=6$ .

Therefore, option B is correct.
