The interpretation of -10c/60 seconds is that the metal loses 10 degrees Celsius every 60 seconds
<h3>How to interpret the expression?</h3>
The expression is given as:
-10c/60 seconds
From the question, we understand that:
The temperature decreases by 10c every minute
When converted to seconds, we have:
10c/60
Hence, the interpretation of -10c/60 seconds is that the metal loses 10 degrees Celsius every 60 seconds

Answer:
the numbers are 85 and -31.
Step-by-step explanation:
first, let the numbers be x and y.
so by question we have,
x+y=54.......(I)
x-y=116......(I I)
now, solve it through elimination method,
x+y=54
x-y=116
here, y and y cancelled out and we get,
or, x+x=54+116
or, 2x=170
or, x=170/2
therefore, x=85
now put value of x in any equation. let's put in eqn (I), we get,
or, x+y=54
or,85+y=54
or, y=54-85
so, y= -31
therefore, the numbers are 85 and - 31.
