Answer:
Step-by-step explanation:
To find the answer to Part A, we can turn this into a simple equation:
192.7 - (2.3 times 25) = temperature, the missing value.
So therefore, after 25 minutes pass, the temperature is equal to
192.7 - 57.5, or:
135.2 = Answer to Part A.
Now, onto Part B. We can use another equation!
192.7 - 2.3x = 100.7
Now, we must solve the given equation, first by taking 100.7 from each side:
192.7 - 2.3x = 100.7
-100.7 -100.7
We are now left with: 92 - 2.3x = 0 - we must now add 2.3x to 2.3x and 0, giving us this:
92 = 2.3x, which is equivalent to 920 = 23x, if that is what you prefer to solve.
To give us our missing value (x), we can divide 920 by 23, giving us: x = 40. This is the answer to Part B: 40 minutes.
I hope this was really helpful! Tell me if you need any more help.
