step-by-step explanation:
we are given
since, we have to isolate x on anyone side
so, we can move all x terms on one side
subtract both sides by 2x
add both sides by 9
divide both sides by 4
we get
3-4
the answer is 3-4 because both 45 and 60 has a multiple of 15.
45/3=15
60/4=15
therefore the odds against selecting a red is 4-3
i believe the correct answer is b.
