He used 53 pounds. I got this by using two equations.
a+b=117
and
5.8a+4.1b= 569.8
I took the first equation and subtracted 'b' so the equation looked like a=117-b.
I then plugged in 117-b into the second equation, so it ended up looking like this:
5.8 (117-b)=569.8
5.8 times 117 is 678.6. And 5.8 times negative b is negative 5.8b.
The equation now looks like this:
678.6-5.8b+4.1b=569.8
Add like terms
678.6-1.7b=569.8
Then subtract 678.6 from both sides
-1.7b= -108.8
divide each side by -1.7
you get b= 64.
But because you are looking for how many pounds for a, subtract 64 from 117. You get 53. 53 is the answer.

Answer:
Explained below.
Step-by-step explanation:
First of all, an integer is a whole number that can be either positive, negative or zero.
Now, a drop in temperature signifies a reduction in the temperature.
This means that if for example, the current temperature is 50 °C, a drop in temperature of 10°C would mean that the current temperature would be gotten by subtracting 10 from 50.
Now,current temperature after drop would be;
T = 50 - 10
To prove that it is gotten by adding a negative integer:
This can also be written as;
T = 50 + (-10)
Because from mathematical multiplication signs, minus multiplied by plus gives minus.
Since, T = 50 + (-10), it means that a negative integer of minus 10 has been added to the initial temperature to get the new decreased temperature.
