Answer:the answer is 12
Step-by-step explanation:
I know this because when 400 divided by 50 withh give you 80 divided by 20 to 20 to 20
The list of two-digit numbers whose digits add up to 10 would be:
19
28
37
46
55
64
73
82
91
Now the numbers have the same digits only reversed and the difference between the two numbers is 18 - the only pair that fits this description is 46 and 64, thus those are the two numbers

Answer:
This is a pretty broad question but im guessing you could use math to calculate how many people would get infected each day. You could start with
Ex.
Okay if we have one infected person how many people could they possibly pass the illness onto the next day. Well if they have x number of classes and see y number of people in those classes whats the PROBABILIITY one of those people gets the virus. Than you could calculate how many people will get infected the NEXT day.
In this question, we're trying to find cost of one sandwich.
To find this, we must make a systems of equation from the given information:
We would represent sandwiches as "s" and drinks as "d".
Systems of equations:
6s + 4d = 53
4s + 6d = 47
Solve for s:
6(6s + 4d = 53)
-4(4s + 6d = 47)
36s + 24d = 318
-16s - 24d = -188
--------------------------
20s = 130
Divide both sides by s
s = 6.50
This means that one sandwich costs $6.50
Answer:
$6.50
