Number Patterns when counting by Tens
When you count by tens the numbers create a pattern. All the numbers end with a zero. The first digits are just like the numbers when you count (1, 2, 3, 4, 5, etc.). This pattern gives the numbers 10, 20, 30, 40, 50, etc.

There are extra periods so I’m not exactly sure but I think it’s 00.96

a ≥ 1 + 6
Step 2. Simplify 1 + 6 to 7
a ≥ 7
86. Is a negative slope because it slants down from left to right.
87. Is positive slope because it slants up from left to right.

To find the percent of change, subtract to find the amount of change
387 - 207 = 180. The increase is 207.
Then divide the amount of change by the original amount
207 ÷ 180 = 1.15
Change the decimal to a percent, and multiply the number by 100:
1.15 X 100 = 115
The answer is 115%
