Answer:

Options A,C and E.

Step-by-step explanation:

The given equation is

2n-9.2=n+\dfrac{4}{5}

Let n be the unknown number, then

Twice a number minus nine and two-tenths is the same as the number plus four-fifths.

2n-9.2=n+\dfrac{4}{5}

So, option A is correct.

Nine point two decreased by double a number is the same as the number added to four-fifths.

9.2-2n=n+\dfrac{4}{5}

Nine point two less than twice a number is equal to the number added to four-fifths.

2n-9.2=n+\dfrac{4}{5}

So, option C is correct.

Two times the difference of a number and nine and two-tenths is equal to the number plus four-fifths.

2(n-9.2)=n+\dfrac{4}{5}

Double a number decreased by nine and two-tenths is the same as the sum of four-fifths and the number.

2n-9.2=n+\dfrac{4}{5}

So, option E is correct.

Therefore, the correct options are A,C and E.

rodikova [14]

Answer: In 5 years it will be worth £455

Step-by-step explanation:

Step 1

Given

The cost of the T.V. for Colin = £530.

The rate of depreciation per year = 3%

Time/ period = 5 years

Formulae to be used

F = P  X (1 - r) ^ n

where

F = the future value after depreciation

P = the present value.

r =the interest rate per time period

n = the time/ periods

Step 2--- SOLVING

F = P  X (1- r) ^ n

F= 530 x (1-0.03) ^ 5

=530 x 0.858734

=£455.129

Rounding up to the nearest penny where appropriate = £455
