It's an equilateral triangle. The angles have measure 60°.
Therefore we have the equations:
6x + 6 = 60 <em>subtract 6 from both sides</em>
6x = 54 <em>divide both sides by 6</em>
x = 9
5y + 10 = 60 <em>subtract 10 from both sides</em>
5y = 50 <em>divide both sides by 5</em>
y = 10
You have to break the number down. (3 x 500) + (3 x 80) + (3 x 4)
Answer: -5<n<=9
Step-by-step explanation:
10n-9>-59
10n>-50
<u>n>-5</u>
n-6<=3
<u>n<=9</u>
n>-5 and n<=9
-5<n<=9
