v = w - 20

move -20 to the other side

sign changes from -20 to +20

to get w by itself

v+20= w-20+20

Answer:

w = v + 20

v = w - 20

v (+ 20) = w - 20 (+ 20)

v + 20 = w

Points B, O, Y are collinear on BY, and BO:OY=5/8. B is located at (4,2), O is located at (7, -3) and Y is located at (x,y). Det
Viktor [21]

Answer:

x = \frac{59}{5}

y = -11

Explanation:

Given that a line segment BY. O is the point lies between B & Y.

Ratio is BO:OY = 5:8

Coordinate of point B = (4,2)

Coordinate of point O = (7,-3)

We will find the coordinate of Y (x,y)

Here we use the section formula.

Internal section formula is :

Y(x,y) =(\frac{mx_{2}+nx_{1}}{m + n},\frac{my_{2}+ny_{1}}{m + n})

(7,-3) =(\frac{5*x+8*4}{5+8} ,\frac{5*y+8*2}{5+8} )

(7,-3) = (\frac{5x+32}{13}, \frac{5y+16}{13})

Now

7  = \frac{5x+32}{13}  

5x+32 = 91

x = \frac{59}{5}

and

-3 =\frac{5y+16}{13}

5y + 16 = -39

y = -11

That's the final answer.

Johan can drive 270 miles on 9 gallons of gas. What is his average mileage?
VladimirAG [237]

Hey there!

The correct answer is 30 miles per gallon.

If he can drive 270 miles on 9 gallons, we want to find the unit rate, or miles per gallon. We can do this by dividing 270 by 9. To make it easier, we will take off the zero, and do 27/9, which is 3. Now we add the 0 back on, which gives us 30. Therefore, his average mileage is 30 miles per gallon.

Have a terrificly amazing day! :D

Let's assume a typical New Zealand farmer raising sheep owns 250 hectares and averages about 10 livestock units per hectare. If
Kipish [7]

Answer:

$50,000

Step-by-step explanation:

We have an average of 10 livestock units per hectare

The number of units in 250 hectares will be;

250 * 10 = 2,500 units

Amount earned per unit is $20 per year

So, for 2,500 units, we have

2500 * $20 = $50,000
