First move the -2 to the other side
Since it is multiplying the brackets we do the opposite and divide 13 by -2
We now have n+3=6.5
Now to get n as the subject we do the opposite of plus 3 so we minus 3 from the other side
So n=3.5

Answer:

<em>XY = 92 units</em>

Step-by-step explanation:

<u>Similar Shapes</u>

Two shapes are similar if all their corresponding side measures are in the same proportion.

The triangles UVW and YVX are similar because their side lengths are in the proportion 1:2, given the tick marks provided in the drawing.

This means that the measure of VX is twice the measure of VW,

The measure of YV is twice the measure of UV

The measure of XY is twice the measure of UW

This last proportion gives the equation:

z + 46 = 2z

Solving for z:

z = 46

Thus, XY = z+46 = 92

XY = 92 units

The slope is -1/2. I know this because slope intercept of a line is y = mx + b. In the equation, y = -1/2 + 1/4, the slope is -1/2 and the y intercept is 1/4.

m stands for slope 
b stands for y intercept

PLEASE ANSWER THIS ASAP !!!!
OLEGan [10]

Answer:

 -4

Step-by-step explanation:

Pick any two points, let's go with (-7, 21) and (-6, 17) to find slope:

slope m = (y₂ - y₁) / (x₂ - x₁)

             = (17- 21) / (-6 - (-7))

             = -4 / 1

         m = -4

---Extra info---

y-intercept using anyone point, let's use (-5, 13) and slope above:

  y = mx + b

  13 = -4(-5) + b

  13 = 20 + b

  b = -7

Equation of line:

y = mx + b

y = -4x - 7

Check:

(-7, 21)

  y = -4x - 7

  21 = -4(-7) - 7

  21 = 21

(-4, 9)

  y = -4x - 7

 9 = -4(-4) - 7

 9 = 9

There are 360 seals. Of them are 9/20 are pups. The rest are adult seals . How many pups are the beach .
k0ka [10]

Answer:

162 pups are on the beach

Step-by-step explanation:

9/20 of 360

The key word "of" tells us to multiply

Variable x = number of pups

9/20 × x/360

Cross multiply

9 × 360 = 20 × x

3,240 = 20x

Divide both sides by 20

162 = x

Check our work:

9/20 = 162/360

Cross multiply

9 × 360 = 20 × 162

3,240 = 3,240

Correct
