The new amount is 36
Step-by-step explanation:
we know that
100%+20%=120%
Let
x-----> the new amount
The number 30 represent the 100%

30/100%=x/120%
x=120*30/100=36

Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
The number of freshmen entering college in a certain year = 621
It is considered as discrete data.
Since we know the definition of Discrete which refers to all types of data which take only numerical values.
It is based on counts.
According to question, we have given the exact number of freshmen instead of any range or interval.
Hence, Third option is correct.
Answer:
VX = 4n +7
explanation:
the equation is VX = n + 7 + 3n, all you need to do is add the n variables and get VX = 4n + 7.
1) Solve one of the equations for either variable.
2) Substitute the expression from Step 1 into the other equation.
3) Solve the resulting equation.
4) Substitute the solution in Step 3 into one of the original equations to find the other variable.
5) Write the solution as an ordered pair.
