Step-by-step explanation:
we know,

Therefore, nth term of a given gp is
16a
Original Income = 15,000
New income = 20,000
The percentage Increase in the income can be calculated as:

%
The change in income = 20000 - 15000 = 5000
Using the values, we get:

%
=

%
This means, Pats income increased by 33.33% in a period of ten years
Answer:
C
Step-by-step explanation:
ok so, assuming that b cannot equal 0, we can divide it on both sides
(3a - 5)/c = b/b
anything divided by itself is 1
(3a - 5)/c = 1
multiply c:
3a - 5 = c
3a = c + 5
a = (c + 5)/3
230
because 5x23 is 115 x 2 which is 230
Answer:
Multiply row 1 by
.
Step-by-step explanation:
The augmented matrix of the system of linear equation is described below:
![\left[\begin{array}{cccc}2&1&-1&-8\\0&2&3&-6\\-\frac{1}{2} &1&1&-4\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D2%261%26-1%26-8%5C%5C0%262%263%26-6%5C%5C-%5Cfrac%7B1%7D%7B2%7D%20%261%261%26-4%5Cend%7Barray%7D%5Cright%5D)
Where
, if we need to create
, we need to multiply row 1 by
, that is to say:
![\left[\begin{array}{cccc}1&\frac{1}{2} &-\frac{1}{2} &-4\\0&2&3&-6\\-\frac{1}{2} &1&1&-4\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D1%26%5Cfrac%7B1%7D%7B2%7D%20%26-%5Cfrac%7B1%7D%7B2%7D%20%26-4%5C%5C0%262%263%26-6%5C%5C-%5Cfrac%7B1%7D%7B2%7D%20%261%261%26-4%5Cend%7Barray%7D%5Cright%5D)
Hence, the correct answer is: Multiply row 1 by
.
