C i believe because they both can break it up those ways even if they might not be the most effective
all correct choices are as follows: a, b, c
The sum of all numbers divided by how many numbers there are total
Answer:
The correct option is;
A 2-column table with 4 rows. Column 1 is labeled Solution steps with entries 3·x minus 15 + 7·x = 65, 10·x minus 15 = 65, 10·x = 80, x = 8. Column 2 is labeled Method to Justify with entries distributive property, addition property of equality, combine like terms division property of equality
Step-by-step explanation:
The question is 3·(x - 5) + 7·x = 65
3·x - 3×5 + 7·x = 65
3·x + 7·x - 3×5 = 65
10·x - 15 = 65
10·x = 65 + 15 = 80
x = 80/10 = 8
Therefore, we have;
Solution steps, Method to Justify
3·x - 15 + 7·x = 65, Distributive property
10·x - 15 = 65, Addition property of equality
10·x = 80, Combine like terms
x = 8, Division property of equality.
