Makovka662 [10]

The cost of TV is $ 792 and cost of DVD player is $ 264

<u>Solution:</u>

Given, total cost of television and dvd player = 1056

The cost of the television is three times the cost of the dvd player.  

Now, let the cost of DVD player be "n", then the cost TV will be (1056 – n)

And, we know that, cost of TV is 3 times Cost of DVD

\text { cost of Television } =3 \times \text { cost of DVD }

\begin{array}{l}{1056-n=3 \times n} \\\\ {1056=3 n+n} \\\\ {4 n=1056} \\\\ {n=264}\end{array}

So, the cost of DVD player is $264, the cost of TV will be (1056 - 264) = $792

Andrew [12]

Answer:

2(b+1+b)= 18

Step-by-step explanation:

Perimeter of a rectangle= 2(l+b)

18 feet= 2(l+b)

length: l, breadth: b

Because the length of the sandbox is 1 foot longer, it will be:

b+1 = l

Substitute l with b+1

2(b+1+b)= 18
