Answer:
x>-7
Step-by-step explanation:
Add positive 2 to both sides
divide both sides by 2
The interval notation that defines this set is: (-∞, -5]

How to graph the inequality?</h3>
Here we want to graph the inequality:
x ≤ -5
This refers to all the values of x equal or smaller than -5.
To graph this, we need to graph a closed circle at -5, and we need to draw an arrow that points to the left (values smaller than -5). The graph is the one that you can see below.
The interval notation that defines this set is: (-∞, -5]
The first end is open, and the second is closed (because of the symbol ≤).

Answer:
<u>m∠CAD is 100°</u>
Step-by-step explanation:
The angles of a triangle always add up to 180 degrees.
Add...
100+x=180
Subtract 100 from each side...
x=80°
m∠CAB=80
-------------
A line is always 180°... line DB consists of m∠CAB (just solved) and m∠CAD (which the answer asks)
m∠CAB+m∠CAD=DB
Substitute in the information we have.
80°+m∠CAD=180°
Subtract 80 from both sides...
<u>m∠CAD is 100°</u>
------------
I hope my answer makes sense to you! :)
What we need to do here is just to isolate h :
60h + 35 >= 245
Subtract 35 from bot sides of the inequation:
60h >= 210
Then divide both sides by 60
h >= 3.5
So they will need to drive at least 3 and a half hours .
