NEVER |-x| would be |x| period
angle 2 = 114°
supplementary angles sum to 180° thus
5y + 16 + 10y + 14 = 180
15y + 30 = 180
subtract 30 from both sides
15y = 180 - 30 = 150
divide both sides by 15
y = = 10
angle 1 = (5 × 10) + 16 = 50 + 16 = 66° and
angle 2 = (10 × 10) + 14 = 100 + 14 = 114°
Answer:
The rules for standard form are
Small numbers can also be written in standard form. However, instead of the index being positive (in the above example, the index was 3), it will be negative. The rules when writing a number in standard form is that first you write down a number between 1 and 10, then you write × 10(to the power of a number)

Hi!
You can turn the decimals into percentages by multiplying the decimal by 100. Multiplying a decimal by 100 turns the decimal into a percentage. So for 0.18, we would do this:
This would give us the percentage, which would be 18%.
We would do the same for 0.7, which would look like this:
Which would give us our percentage, which would be 70%.
On conclusion, the formula for turning a decimal into a percentage is:
Hope this helps! Good luck!
