Answer:
The first number is 20, the second one is 11
Step-by-step explanation:
Let the first number be x and the second number be y
Since it says "9 is the difference between two numbers", the first equation will be x-y=9
It also says that "their sum is 31". That means the second equation will be x+y=31
here are the two equations:
x-y=9
x+y=31
You can solve this any way you like, but I'll show elimination
add the two equations
x-y=9
x+y=31
2x=40
divide by 2
x=20
Substitute 20 as x in one of the equations
20+y=31
subtract 20 from both sides
y=11
That means the two numbers are 20 and 11
Hope this helps!

I added 1 tenth to the answer.I'm sorry if the answer if wrong. math isnt my best just trying to help
<span>To subtract 3 3/8 from 5 1/2,
by turning into fractions
</span><span>[(5x2)+1]/2 = 11/2
</span><span>[(3x8)+3]/8 = 27/8
</span><span> 11/2 - 27/8
</span>To subtract fractions, your denominator needs to have the same number. so multiply it by 4
44/8 - 27/8 = (44-27)/8 = 17/8.
17 / 8 pounds or 2 and 1/8 because 17 / 8 = 2 remainder 1.
<span>In terms of weight that is 2.125 pounds.</span>
