Find the output, d, when the input, t, is 11.


d = -20+11t

d= __

Answer 1

d = 101

Explanation:

d = -20 + 11t Substitute 11 for t in the equation

d = -20 + 11(11) Multiply in the parentheses

d = -20 + 121 Add

d = 101

Answer 2

Substitute the given value into the equation


-20 + 11*11

Using BODMAS, you do 11*11 first, which is 121


-20+121

Which is 101

Therefore, d is equal lot 101
