Answer:
Step-by-step explanation:
We are given the temperature inside the machine from startup until 10 seconds later, the formula is:
We want to know at what time t the temperature inside the machine will be equal to 128 °C.
So we set:
Now, we rearrange the equation to keep terms with t on the left hand side and terms without t on the right hand side
and we simplify:
now it's easy to solve for t:
And thus we arrive to the solution.
When
you would have to use comon multiples to find what both numbers have in common, a short way of finding this would be
where (a) is the answer of the equation, (a) would be 2 because 8*2=16 meaning
