If you mean: (3x)^-1
When you have a power to a negative number (1 in this case), place the power on the numerator, with the base in the denominator.
(3x)^-1 = 1/3x
1/3x, or C) is your answer
hope this helps

Answer:
63
Step-by-step explanation:
The number of seats in a row will give an arithmetic sequence:
6, 9, 12, 15, ...
The first term is 6; the common difference is 3. The general term is ...
an = a1 +d(n -1) . . . . . . n-th term of sequence with first term a1, difference d
The 20th term of the sequence is ...
a20 = 6 +3(20 -1) = 6 +57 = 63
There would be 63 seats on the 20th row.
We can put the two equations together with substitution, and we get
3x + 2y = 30
Now we have a single equation in two variables, so we don't have enough information to solve for both x and y.
Answer:
2 5/6
Step-by-step explanation:
9 5/12 - 6 7/12
We will need to borrow from the 9
8 12/12 + 5/12 - 6 7/12
8 17/12 - 6 7/12
(8-6) + (17/12 -7/12)
2 10/12
This simplifies. Divide the top and bottom of the fraction by 2
2 5/6
Answer:
the answer would be 135 meters
Step-by-step explanation:
If, to scale on a map, 1 centimeter is 3.5 meters, them 2 centimeters is 7 meters. so on and so forth until 30. 30 (centimeters) times 3.5 (meters) is 135. hope this helped!!!!! reply if this doesn't make sense
