PLS help<br> solve for x: -6(2x-5) = 18

Mashutka [201]

Hey!

$-6(2x-5) = 18$

Switch it around and it becomes:

$2x - 5 = 18 \div -6$

First find 18 ÷ -6

$18 \div -6 = -3$

Positive ÷ negative OR negative ÷ positive is always negative.

That leaves you with:

$2x - 5 = -3$

Switch that around and it becomes:

$-3 + 5 = 2x$

Find -3 + 5

$-3 + 5 = 2$

That leaves you with:

$2 = 2x$

Divide both sides by 2 to leave <em>x</em> alone

$\frac{2}{2} = \frac{2x}{2}$

$\framebox{x = 1}$

Find the value of k if the distance between (2,k) and (6,7) is 4√2 unit

andreyandreev [35.5K]

Answer:

k = 3

Step-by-step explanation:

We have the distance formula: $d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}$ . We can plug in $4\sqrt{2}$ = d, x2 = 6, x1=2, y2 = 7, y1 = k.

Then, we can solve the question using some algebra to find that k = 3.

Edit: Here is a step by step:

$4\sqrt{2} = \sqrt{(6-2)^2 + (7-k)^2}\\$

$(4\sqrt{2})^2 = (6-2)^2 + (7-k)^2$

$32 = (4)^2 + (7-k)^2$

$32 = 16 + (7-k)^2$

$32 - 16 = (7-k)^2$

$16 = (7-k)^2$

$\sqrt{16} = (7-k)$

$4 = 7-k$

$k = 3$
