Answer:
A Subtract 6 from 27 then divide by 3
Step-by-step explanation:
3B + 6 = 27
3B = 21
B = 7
so you subtract 6 from 27, then divide by 3
15.5, because 31 divided by 2 is 15.5. And all the other number divided by the number below them also turns out to be 15.5.
Hope this helps. :)
80 inches or feet.. I think you are suppose to multiply 40x2 sorry if im wrong
Answer:
Proof in explanation.
Step-by-step explanation:
I'm going to attempt this by squeeze theorem.
We know that
is a variable number between -1 and 1 (inclusive).
This means that
.
for all value
. So if we multiply all sides of our inequality by this, it will not effect the direction of the inequalities.

By squeeze theorem, if 
and
, then we can also conclude that
.
So we can actually evaluate the "if" limits pretty easily since both are continuous and exist at
.

.
We can finally conclude that
by squeeze theorem.
Some people call this sandwich theorem.
