They rented out 5 self-propelled mowers and 20 riding mowers.
Data;
- Total number of tool rented out = 25
- Cost of tools rented = $900
To solve this problem, we have to write a system of equations to represent the problem.
since we have
- x = self - propelled mower
- y = riding mowers
Let's write equations with these variables.
From equation (i)
Put equation (iii) into equation (ii)
Let's substitute the value of y into equation(i)
From the calculations above, they rented 5 self-propelled mowers and 20 riding mowers.

Answer:
AP= 12
Step-by-step explanation:
Here is the complete question: If the length of AB=12, what is the length of AP? picture attached.
Given: AB= 12
∠APB= 60°
Remember; sum of all angle of triangle is equal to 180°.
We can look at picture, where two side of triangle is radius of circle.
∴ Angle of two side will also be same for the isosceles triangle.
Lets assume the unknow angle of the triangle be "x".
Now,
⇒ 2x+60= 180
subtracting both side by 60
⇒
∴
As now we have all the angle of triangle is 60° (equilateral triangle)
∴ All the side will be same, which is 12
Hence, AP= 12.
