If (x-2)/3= y and y=4, what is the value of x?
X= 14 If you replace Y with 4 in the first equation, you get (X-2)/3=4. Then multiply both sides by 3 to get rid of the denominator on the left. Now you have X-2= 12. Now add 2 to both sides and you have x= 14.
A jar contains 84 gummy bears- 12 white, 25 green, 19 purple, 20 blue, and 8 yellow. If a bear is chosen at random, what is the probability that the bear will be neither green nor white?
.559 This is the answer because if you're considering the probability of choosing a bear that's neither white NOR green, you have to consider how many bears are present that are not these colors. In this case, there are 47 bears that aren't white or green, so the probability of pulling of these bears is 47/84 which is .559.
