use algebra tiles to solve 5n + 2 = 3n + 8. (do this on paper. your instructor may ask you to turn in this work.) show the corresponding algebraic representation. 5n + 2 = 3n + 8
5n + 2 − 2 = 3n + 8 −
5n = 3n +
5n − 3n = 3n + 6 − __n
2n =__
2n ÷ 2 = 6 ÷ n =

n=3.

Step-by-step explanation:

5n+2=3n+8

We substract 2 in both sides to cancelate the 2 in left:

5n+2-2=3n+8-2

5n=3n+6

We substract 3n in both sides to cancelate the 3n in right:

5n-3n=3n+6-3n

2n=6

Finally, we divide by 2 in both sides to clear n:

2n/2 = 6/2

n=3.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
