Step-by-step explanation:
In order to calculate that, you need to substitute for x = 20
t(20) = 20 + 0.029(20)
t(20) = 20 + 0.58
t(20) = 20.58
In short, Your Answer would be 20.58
Hope this helps!
Expand
(6a + 18 = 18 + 6a)
Cancel 6a on both sides
(18 = 18)
Since both sides are equal, there are infinitely many solutions.
