Let s represent the sandwich and p represent the portion
<span>s=8p</span>
Answer:
s+23–s=4.3+s: 1 solution
25+3=2s+-45
: 1 solution
Step-by-step explanation:
L=17.49635531
W=5.715476066
100 = L X W
L = 2+ 3W
Insert the L equation into the 1st equation, 2+ 3W x W = 100
<span>2+ 3W x W = 100
</span>-2 -2
3W X W = 98
3W^2 = 98
Divide both sides by 3
W^2 = 32.66
Square root both sides
now you have the Width, plug the width into the L X W = 100 equation, then divide 100 by the width, and now you have the length.

You may consider a function with domain 
and switch 
For example, we know that
can only be evaluated for positive values of the argument. This means that
can also be evaluated only for positive values of the argument, i.e.
To give another example, you may consider a function with domain 
, consider its inverse to remove 0 from the domain, and finally switch again :
