Answer:
$3
Step-by-step explanation:
23-17=6
6/2=3
To check:
6+17=23
There are 91 in total. Since there are 21 red cars, it would give you 21/91. Around a 23.07% chance.
-3/5x + 1/5 > 7/20
-3/5x > 7/20 - 1/5
-3/5x > 7/20 - 4/20
-3/5x > 3/20
x < 3/20 * - 5/3
x < -15/60 reduces to -1/4
Just divide the y numbers by the x numbers and that's it
