Answer:

A = 110.25

Step-by-step explanation:

add all the equations and equal it to 180 because all triangle angles add to 180:

4x+1 + 3x + 3x-1 = 180

10x =70

/10 /10

x = 7

Insert x into each equation and solve:

3(7)-1 = 20

4(7)-1 = 27

3(7) = 21

and then use A = 1/2 base*height formula:

A= 1/2 21* 20

A= 210

Farmer Kipp sold 25 horses for a total of $7500 in January and 25 horses for a total of $10500 in February. What is the average

insens350 [35]

Answer:

So Average Price of horse is $360

Step-by-step explanation:

Given:

25 horses sold in January for $ 2500

25 horses sold in February for $10500

TO find:

Average price of horse = ?

Solution:

Average price is usually found out by adding all the values and dividing by its total no of values

Now in our case

Total Horse = 25 + 25

= 50

Total Money = $7500 + $10500

= $18000

Average Price $=\frac{total price}{total horses}$

Average Price $=\frac{18000}{50}$

=$360

So Average Price of horse is $360
