Answer:
Step-by-step explanation:
Angles <em>B</em><em> </em>and<em> </em><em>C</em><em> </em>form a straight angle, so you set both expressions equal to 180°:
180° = (2x + 15)° + x°
180° = 15° + [3x]°
- 15° - 15°

![\displaystyle \frac{165°}{3°} = \frac{[3x]°}{3°} \\ \\ 55° = x](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B165%C2%B0%7D%7B3%C2%B0%7D%20%3D%20%5Cfrac%7B%5B3x%5D%C2%B0%7D%7B3%C2%B0%7D%20%5C%5C%20%5C%5C%2055%C2%B0%20%3D%20x)

Answer:
Yes, -13 is less than f/2.
Step-by-step explanation:
Since we are given a fraction with a variable, it may seem hard at first to find out which number is greater.
First, we have to realise that -13 is a negative number. Any negative number is always equal to less than a positive number.
Whatever number we replace our variable f with, whether it be 2, 3, 9, or 0.00000000000001, we can rest assure that it will be a <em>positive</em> number.
Since positive numbers are greater than negative ones, -13 has to be less than f/2.
If the fraction was negative (- f/2), this would be a nearly impossible question to answer.
<span>2x-3y=3
3y = 2x - 3
y = 2x/3 - 1
