The square root of 6x-38 = x-5Solve for x

(first correct answer gets brainliest)
(it is the square root of both 6x and 38)

Answers

Answer:

The solution set is = {7, 9}.

Step-by-step explanation:

√(6x - 38) = x - 5

Square both sides:

6x - 38 = (x - 5)^2

x^2 - 10x + 25 - 6x + 38 = 0

x^2 - 16x + 63 = 0

(x - 7)(x - 9) = 0

x = 7, 9.

Check these solutions:

x = 7:

√(6x - 38) = √(42-38) = 2 and 7 - 5 = 2 so this is correct.

x = 9

√(6x - 38) = √(54 - 38) = √16 = 4 and 9 - 5 = 4 so 9 is also correct.

Answer:

{7, 9}

3/4 of a number is 27. What's the number

It's 36 because 36 divided by 4 is 9, multiply that by 3 and you get 27.

What is the value of y?6(5 + 3) = 6 • 5 + 6 • y

y =

Answers

Divide the equation by six to get:

5+3=5+y

Subtract 5 from both sides to find that y=3.

$6(5 + 3) = (6 *5) + (6 * y) ~~\to~~ 6(8) = 30+ 6y \to 48 = 30 + 6y$

$6y=18 \to y=3$

y=3

Hope that helps :)
