When t = 9 and u = 11, the value of the expression 3 + 11t - 9u is calculated as: 3.
How to evaluate an expression?
To evaluate the expression 3 + 11t - 9u when t = 9 and u = 11, substitute these values into the expression:
3 + 11t - 9u
Replace t with 9 and u with 11:
3 + 11(9) - 9(11)
Now, perform the operations:
3 + 99 - 99
Combine the terms:
= 3
So, when t = 9 and u = 11, the value of 3 + 11t - 9u is 3.
