53m- 35
(49m-53) + 10
(30m + 21m) + (18-2m)
51m + (-53 + 18) - 2m

Answer 1

It looks like you've provided a series of mathematical expressions involving variables, likely representing values in meters (denoted by "m"). Here’s a breakdown of each expression:

1. **53m - 35**: This is a linear expression, simplifying to a value of 53m minus 35.

2. **(49m - 53) + 10**: This can be simplified to 49m - 53 + 10, which further simplifies to 49m - 43.

3. **(30m + 21m) + (18 - 2m)**: First, combine like terms in brackets: 30m + 21m equals 51m, so you have 51m + (18 - 2m). This simplifies to 51m - 2m + 18, resulting in 49m + 18.

4. **51m + (-53 + 18) - 2m**: Simplifying the expression in the parentheses: -53 + 18 equals -35. So it becomes 51m - 35 - 2m, which simplifies to (51m - 2m) - 35, resulting in 49m - 35.
