3k+7k-2 = 6k+18

10k -2 = 6k +18

4k = 20

k=5

XP = 35-2 = 33

If X is between P and Q, then PQ is the whole line segment and XQ and XP are line segments that add up to PQ. Therefore, you can make an equation where XQ and XP add up to PQ.

XQ + XP = PQ

(3k) + (7k - 2) = 6k + 18

Combine like terms.

10k - 2 = 6k + 18

Add 2 to both sides.

10k = 6k + 20

Subtract 6k from both sides.

4k = 20

Divide both sides by 4.

k = 5

Plug 5 for k into XP.

XP = 7(5) - 2 ⇒ 35 - 2

XP = 33

What is the equation of the line, in slope-intercept form, that passes through (3, -1) and (-1, 5)? y = -3/2x+7/2 2y = -3x + 7 2
SOVA2 [1]

Answer:

The equation of the line would be y = -3/2x + 7/2

Step-by-step explanation:

In order to find this, we must first use the slope formula with the two point to find the slope.

m(slope) = (y2 - y1)/(x2 - x1)

m = (5 - -1)/(-1 - 3)

m = 6/-4

m = -3/2

Now that we have the slope, we can use that and either point in point-slope form. Then we solve for y.

y - y1 = m(x - x1)

y + 1 = -3/2(x - 3)

y + 1 = -3/2x + 9/2

y = -3/2x + 7/2

A small box weighs 1 25 pounds. A large box weighs 3 1/3 time as much as the small box. how much does the large box weigh?
egoroff_w [7]

Answer:

416.7pounds

Step-by-step explanation:

Given parameters:

         Weight of the small box  = 125pounds

Unknown:

Weight of the larger box = ?

Solution:

The large box weighs 3\frac{1}{3} times as the small box:

               So;

                =   125pounds x \frac{10}{3}

                = 416.7pounds
