Answer:
Pythagorian theorem:
7^2=13+b^2 -> b^2=49-13=36
The square root of 36 is obviously 6.
So, the other leg has a length of 6 inches
Step-by-step explanation:
What we have to solve is:

we should multiply both sides by10, to get the "x" by itself:



so there are 8 tenths in this number!
The answer is 7.
f(a) = 2a-1, 3f(a) = 3(2a-1) = 15 -> a=2 so f(2a)=f(4)=7
Yes. There are 2 decimal places in .51 and 3 in 2.427.
So there would be a total of 5 decimal places.
n - 8 < -8
< is similar to = in this case
n < -8 + 8
n < 3
The answer would be bubble #3.
