9 is the difference between two numbers, and their sum is 31. Find the numbers.
algol [13]

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!

Ginger's baby weighed only 3 3/8 pounds when it was born. The doctor said it could not leave the hospital until it weighed 5 1/2
Elanso [62]
<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>
