3(8 + 6n) = 6n - 12
equals n = -3.
First, expand. Your problem should look like: 24 + 18n = 6n - 12.
Second, subtract 6n from both sides. Your problem should look like: 24 + 18n - 6n = -12.
Third, simplify 24 + 18n - 6n to 24 + 12n. Your problem should look like: 24 + 12n = -12.
Fourth, subtract 24 from both sides. Your problem should look like: 12n = -12 - 24.
Fifth, simplify -12 - 24 to -36. Your problem should look like: 12n = -36.
Sixth, divide both sides by 12. Your problem should look like: n = -
.
Seventh, simplify
to 3. Your problem should look like: n = -3, which is your answer.
Answer:
Last year we had M students.
This year we have N students.
Now, the question ask "by what percentage the number of students grow".
So we are considerating a growth, this means that we must think that M as the 100%.
Then we have that N - M is the difference between the students of last year and this year.
this means that this year we have N - M more students that last year, so the percentage of growth is:
((N - M)/M)*100%
Now you need to replace the values for N and M.
You also can notice that if N is smaller than M, you will have a negative percentage, this means that instead of a growth, we have a decrease in the number of students.
It is important to go through details that are provided in the question. Based on those details the answer to the question can be easily deduced.
Let us assume the number of lions at the zoo = x
Number of male lions in the zoo = 2
Then
(1/6) * x = 2
x/6 = 2
x = 2 * 6
= 12
So there are a total of 12 lions in the zoo. I hope the procedure is clear enough for you to understand. Using this method, it will be possible for you to do similar problems in future without requiring any help from outside. Only be careful about the calculation part.
Answer:
B
Step-by-step explanation:
It is not A because if they were riding for a constant speed the entire ride it would just be a straight line going up and that line is curved.
It is B because in the chart you see that from hour 3 to hour 4 they did not move at all (this is why it is a flat horisontal line) and you can infer that they stopped and took a break.
It is not C because they stopped and took a break at hour 3 to hour 4.
It is not D because they never decreased their milage.
