The cost of 2 tv is 4 times more cost one DVD ;
The cost of 2 tv and 3 DVD player is 7 times more cost one DVD ;Then, 1 DVD cost 1421 ÷7 = 201 $ ;
1 tv cost = 2 * 201 = 402 $ ;
Final answer:
To solve the problem, you set up two equations based on the information given. Then, you substitute one equation into the other to solve for the cost of the TV, which comes out to be approximately $405.43.
Explanation:
To answer this question, you need to use algebra. We can create two equations based on the information given. Let's say the cost of a TV is x and the cost of a DVD player is y. According to the problem, we have two equations:
- 2x + 3y = $1421 (This comes from the total cost of the 2 TVs and 3 DVD players)
- y = 0.5x (This comes from the fact that the cost of a DVD player is half the cost of a TV)
We can then substitute the second equation into the first to get:
- 2x + 3(0.5x) = $1421
- 2x + 1.5x = $1421
- 3.5x = $1421
To find the cost of the TV 'x', you can divide both sides of the last equation by 3.5 resulting in x = $405.43. So the cost of one TV is approximately $405.43.

An automated car wash can wash 120 carsin 20 hours.
What is expression?
In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.
Given is that an automated car wash can wash 30 cars in 5 hours.
Now, an automated car wash can wash 30 cars in 5 hours.
Then, 1 car can be washed in (5/30) hours.
So, 120 cars will take (5/30 x 120) hours
(5/30 x 120)
5 x 4
20 hours
Therefore, an automated car wash can wash 120 carsin 20 hours.
