Answer:
12. C
13. A
Step-by-step explanation:
Let's use some examples. So what can you make with 16? You can make 1 and 15, 2 and 14, etc.
How about trying 1 and 15 first?
1*15 = 15
What about 2 and 14, 3 and 13, and 4 and 12?
2*14 = 28
3*13 = 39
4*12 = 48.
Now we notice a pattern-- the numbers keep getting bigger, right? So the closer you get to the middle, the bigger the area will get. So if we divide 16 by 2, we get 8. Let's try 8 and 8.
8*8 = 64
That's larger than 48! Now let's try a couple more to make sure.
9*7 = 63
10*6 = 60
11*5 = 55
Next time, you'll know that with one of these problems, the biggest area would be the two numbers closest to each other you can get. Hope this helps! :)
The answer for this is Substitution property
Substitution Property is considered as one of the most intuitive of the mathematical properties that you'll probably encounter. You may have been using substitution without even knowing it. This property says that if x=y, then in any true equation involving y, you can replace y with x, and yet you'll still have a true equation.
Take a look at the attached example shown below.

Answer:
n=10
Step-by-step explanation:
6=3n/5
multiply both sides by 5
30=3n
divide both sides 3
10=n
