P(n) = n + 1
since 6 replaced the n, plug in 6 where n use to be in the expression
P(n) = n + 1
P(6) = (6) + 1
P(6) = 6 + 1
P(6) = 7
P(6) = 7 is your answer
hope this helps
Simplified it's 7h-v =6 because you move the variable you want to find out to one side by doing to opposite thing to both sides (+4 is -4)
Here you go :) . . . . ..
Answer:
true because it have no common solution
The student would have to score 100% on their next test to brung their average up to 90. Here is why;
90+84+86=260
(260+?)/4=90
(260+100)/4=90
360/4=90
This is done to get the mean (or average) of a group of numbers by adding all the numbers and dividing by the amount of numbers you added together. Here it is divided by 4 because of the three tests he has taken and the test he will take.
