That is way too much questions for one sitting. If you really struggle that much, download this app called photomath. You take a picture of one of the questions and then it instantly solves it and shows the work so you know how to do it.
For 16-25 however, you would need to rewrite your questions on a blank piece of paper with the variables substituted in. So let's say:
a + b² - (c-2).
You would need to rewrite it as the following in order for the app to solve it.
12 + 9² - (4 -2)

Step-by-step explanation:
i think its right
-12x - 0.4 > 0.2(36.5x + 80) - 55 Remove the brackets.
-12x - 0.4 > 7.3x + 16 - 55 Combine the like terms on the right
-12x - 0.4 > 7.3x - 39 Add 12x to both sides
- 0.4 > 7.3x + 12x - 39
- 0.4 > 19.3x - 39 Add 39 to both sides.
-0.4 + 39 > 19.3x Combine like terms on the left
38.6 > 19.3x Divide by 19.3
38.6 / 19.3 > x
2 > x
