We'll do the first one. I can't read the variable, but it looks like a

so that's what I'll use, but it doesn't matter.
First, get the variable by itself:

You get that before you multiply each side by two.
Now, you color the line so that all values that are less than 6 are shaded, so you put an open circle at 6 since it's not included and then you shade everything to the left.
Since there are 3 "2's" and 8 total options, the probability is 3/8 or C.
The answer is:
7 miles
5+2=7
<u><em>Both the statement and its contrapositive are true. </em></u>A right angle will always be 90 degrees, so both are true.
Answer:
b= -10
Step-by-step explanation:
9^ -8 * 9^ -2
We know that a^b * a^c = a^ (b+c)
9^ (-8+-2)
9^ -10
We want it in the form a^b
a=9
b= -10
