Answer:
Step-by-step explanation:
There are <u>6</u><u> different shapes</u>
You want the outcome to be a Nonagon
You put the outcome as a ratio 1/6
1/6=0.1666667
0.1666667*100=16.6667%
<u>Chance of pulling out a </u><u>nonagon</u>
Answer:
The answer is x + 160 = 459
Step-by-step explanation:
You can find this answer by understanding what the variable is. Once you find that the rest is easy. You know that the cost of the peak II is $459. You also know that the peak II is $160 more than rider/variable so, 459 - 160 = 299
Answer:
C. 2x + 5
Step-by-step explanation:
Kelly: x
Tim: 2 × x = 2x
Jim: 2x + 5
hope it helps :)
We can use the points in either order and you will still get the same slope. I usually solve in order that is given. So the first coordinates I label (x1,y1) and the second is (x2,y2).
Slope=m=(y2-y1)/(x2-x1)
m=(9-5)/(3-1)=4/2=2
Slope is 2.
