Answer:
see below
Step-by-step explanation:
sqrt(77)
8^2 = 64
9^2 = 81
It is closer to 9
We know it is between 8.5 and 9
8.8^2 = 77.44
This is a good approximation
First the person with a flashlight and one of his friends cross the bridge. After that same person with a flashlight comes back and leads another friend to the other side. Finally he comes back again and leads the last of them.

Answer:
x>1
Step-by-step explanation:
In order to do this, we can take the inequality:
3+2x>5
now there are constants on both sides meaning we can combine them like the following:
3+2x>5
-3 -3
------------
2x>2
Now we can simplify
2x/2>2/2
therefore, the answer is x>1
In order to graph this on a line you would need to put in a circle which is not filled in because x isn't <u>equal to and greater than</u> 1 so we put in a blank circle and since x is always going to be greater than 1, we would put a line that keeps going on.
You would put this line to the right of 1
o----------->
1 2 3 4 5 6
that is how the line would look like
The only answer I could think of is Ice-sosceles traingles?
3x+4y = 15
4y = -3x + 15
y = -3x/4 + 15/4
y = (15 -3x)/4
answer is the first one.
1. y = (15 -3x)/4
