What is an expression?
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.
Given that John cashed a check for $630. The teller gave him three fifty-dollar bills, eighteen twenty-dollar bills, and t ten-dollar bills.
The value of t will be calculated as:-
3 x 50 = 150
18 x 20 = 360
Total bill is, 360+150 = 510. Then subtract the value 510 from 630.
$630 - 510
$120
120 / 10 = 12
Therefore, the value of t will be equal to $12.
