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

What is the value of x ?

zimovet [89]

Each angle of the triangle added together must be equal to 180, so 53+45=98. 180-98=82. So the top angle is 82, the value of x has to be equal to 180-82 which equals 98

Helpppp pleaseeeee and could you put an explenation??? pleaseeee

Illusion [34]

Answer:

Step-by-step explanation:

The angles would be supplementary

45 + 5x + 35 = 180

5x + 80 = 180

5x = 100

x = 20

To find out why they are supplementary, refer to the transversal below

∠3 = ∠7 (corresponding angles)

∠8 = 180 - ∠7 (supplementary angles)

And since ∠7 = ∠3...

∠8 = 180 - ∠3 which is why (in the problem) those two angles are supplementary (adding to 180 degrees)
