Answer:
3n^2
Step-by-step explanation:
3, 12, 27, 48, 75
List the differences between terms:-
9, 15, 21, 27
Now find the second differences:-
6, 6, 6
The sequence in the question is quadratic and the first coefficient ( that of n^2) = 6/2 = 3. The first term in the nth term formula is 3n^2.
Now we write out the original sequence and the 3n^2 values as follows:-
3 12 27 48 75
3 12 27 48 75
They are the same so the formula for the nth term is 3n^2.
I haven't done anything like this in a while. my guess would be 4/11 as a reduced fraction. no promises this is correct!
Answer: sale: 536
discount: 33%
33/100*536=
Step-by-step explanation:
1- I assume the cost of the suit is $536, not 536%.
So the % of the part times $536= Original price
Remember, $536 is 77% of the original price.
536x0.77=$696.10
Since the suit was 33% off, and since the sale price of the suit was $536
Then the suit was sold for 67% of its original price
Therefore, 67% of its original price (p) equals $536, or .67(p) = 536
.67p = 536
p = 536 � .67 = $800
Original price of suit was $800
Answer:
2/3x - 3 = 5
Step-by-step explanation:
Let x be the number
2/3x - 3 = 5
Add 3 to each side
2/3x-3+3 = 5+3
2/3x = 8
Multiply each side by 3/2
3/2*2/3x = 8*3/2
x = 12
The answer is C
y=kx. where k is a constant
sub y=34,x=2
2k=34
k=17
