Answer: 12 cupcakes have vanilla icing.
Step-by-step explanation:
We know that Joakim is icing a total number of 30 cupcakes.
According to the exercise, Joakim spreads mint icing on 
of the cupcakes.
Let be "m" the number of cupcakes that have mint icing. Then
He spreads chocolate on 
of the remaining. The remaining is:
Let be "c" the number of cupcakes that have chocolate. Then
Let be "v" the number of cupcakes that have vanilla icing.
Since the rest will get vanilla icing, we know that:
Let us calculate the speed of each conveyor belt. The bigger one does 300 pounds in 10 minutes, hence its speed is 300 pounds/ 10 minutes=30 pounds/min. The smaller one needs 30 minutes, hence its speed is 300 pounds/ 30 minutes=10 pounds/min. We see that the total speed of both machines if they work together is 30+10=40 pounds/min. We have then that the two machines together can transfer 300 pounds in 300/40=7.5 minutes.
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. In plain English, the definition means: The range is the resulting y-values we get after substituting all the possible x-values
Answer:
12 - 4
Step-by-step explanation:
To get the range, subtract the lowest number from the highest
The highest number is 12
The lowest number is 4
Range = 12 - 4
= 8
X=2 because 3 times 2 is 6 and then you add 6 and 7 together and get 13.
