Answer:
a) the number you start off with is 10
Step-by-step explanation:
1) you are trying to figure out what you started off with to get 60, so you are going to work backwards to see how you got that
2) to do that, you should start from 60. so half of x should be double 60, since it states x divided by 2 is 60, so double 60 is 120
3) after that, three times what number did you do to get 120? to get that, you should divide 120 by 3 since you multiplied it 3 times, which is 40 that gets multiplied 3 times
4) check your work. 40 multiplied 3 times is 120, and 120 divided by 2 is 60, which is the final answer.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
It is given that difference of three times a number and half the number is 60.
The number will be calculated as below:-
Let the number be x. The expression will be written in a mathematical form as below":-
3x - (x/2) = 60
(6x - x)/ 2 = 60
5x / 2 = 60
x = 120 / 5
x = 24
Therefore, the number for the expression will be equal to 24.
