3x-18=42
-18=-18
3x= 24
/3. /3
x=8
Answer:
Step-by-step explanation:
Firstly add all the probabilities together
10 + 8 + 42 = 60
42 White Cars drove by
This can be displayed as 42/60
I do believe that you do not need to simplify Probabilities but you can if you want.
we use equation 1 first.
-2x -y = -9
-y = -9 + 2x
y = 9 -2x
We substitute value of y in equation 2
5x - 2 (9 - 2x) = -9
5x -18 - 4x = -9
5x - 4x = -9 + 18
x = 18 -9
x = 9
We now find the value of y
-2x -y = -9
-2 (9) - y = -9
-18 - y = -9
-y = -9 + 18
y = 9 - 18
y = -9
Answer:
