Answer:
184
Step-by-step explanation:
First, you want to establish your equations.
L=7W-2
P=60
This is what we already know. To find the width, we have to plug in what we know into P=2(L+W), our equation to find perimeter.
60=2(7W-2+W)
Now that we only have 1 variable, we can solve.
First, distribute the 2.
60=14W-4+2W
Next, combine like terms.
60=16W-4
Then, add four to both sides.
64=16W
Lastly, divide both sides by 16
W=4
To find the length, we plug in our width.
7W-2
7(4)-2
28-2
L=26
0.015 or 3/200
15 divided by 1000 is 0.015
15/5 is 3 1000/5 is 200
Answer:
$4.80.

The probability of not selecting green or yellow marble is equal to the probability of selecting red and blue marble
n(S) =17
n(A)=5 (red)
n(B)=6 (blue)
answer is 5+6/17
=11/17
