Which statement is correct?

Y_Kistochka [10]

Answer:

We can conclude that only option B is correct.

Step-by-step explanation:

A. The equation 3(3x - 2) - 4 = 5x has a solution.

Solving it we get,

3(3x - 2) - 4 = 5x

⇒ 9x - 6 - 4 = 5x

⇒ 4x = 10

⇒ x = 2.5

B. The equation 4(2x - 3) - 5 = 4x has exactly one solution.

Solving it we get,

4(2x - 3) - 5 = 4x

⇒ 8x - 12 - 5 = 4x

⇒ 4x = 17

⇒ x = 4.25

C. The equation 5(3x - 2) - 2 = 3x also has exactly one solution.

Solving it we get,

5(3x - 2) - 2 = 3x

⇒ 15x - 10 - 2 = 3x

⇒ 12x = 12

⇒ x = 1

D. The equation 6(2x - 3) - 3 = 2x also has exactly one solution.

Solving it we get,

6(2x - 3) - 3 = 2x

⇒ 12x - 18 - 3 = 2x

⇒ 10x = 21

⇒ x = 2.1

Therefore, we can conclude that only option B is correct. (Answer)

How do I solve this?

Korolek [52]

(x−8)2=(x+−8)(x+−8)=(x)(x)+(x)(−8)+(−8)(x)+(−8)(−8)=x2−8x−8x+64=x2−16x+64

(x−8)2=x2−82Step 1: Simplify both sides of the equation.x2−16x+64=x2−64Step 2: Subtract x^2 from both sides.x2−16x+64−x2=x2−64−x2−16x+64=−64Step 3: Subtract 64 from both sides.−16x+64−64=−64−64−16x=−128Step 4: Divide both sides by -16.−16x−16=−128−16x=8

a television and dvd player cost a total of $1056. the cost of the television is three times the cost of the dvd player. find th

Makovka662 [10]

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

Solution:

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

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