3x + 1 = 8
move +1 to the other side
sign changes from +1 to -1
3x+1-1= 8-1
3x= 7-1
divide by 3 for both sides to get x by itself
3x/3= 7/3
Answer:
x= 7/3 and x= 2 1/3

Answer:
The quiz grades for class 1 have more variability than the quiz grades for class 2.
Step-by-step explanation:
Given that the cubical piece has side (s) 7 mm, and a cylindrical hole of diameter (d) as 3 mm.
The volume of the piece can be calculated as,

It is mentioned that the material costs $207 per cubic meter, so the cost (c) of 1 piece is calculated as,

This is the cost (in dollars) for 1 piece.
Given that the manufacturer wants to produce 1,000,000 such pieces, so the total cost (TC) is calculated as,

Thus, the total prototypes will cost around $60.75
