They rented out 5 self-propelled mowers and 20 riding mowers.
Data;
- Total number of tool rented out = 25
- Cost of tools rented = $900
<h3>System of Equations</h3>
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.
![x+y = 25...equation (i)\\20x+40y = 900...equation(ii)](https://tex.z-dn.net/?f=x%2By%20%3D%2025...equation%20%28i%29%5C%5C20x%2B40y%20%3D%20900...equation%28ii%29)
From equation (i)
![x+y= 25\\x = 25 - y...equation(iii)](https://tex.z-dn.net/?f=x%2By%3D%2025%5C%5Cx%20%3D%2025%20-%20y...equation%28iii%29)
Put equation (iii) into equation (ii)
![20x+40y=900\\x = 25-y\\20(25-y)+40y=900\\\\500-20y+40y=900\\500+20y=900\\20y=900-500\\20y=400\\\frac{20y}{20}=\frac{400}{20}\\ y=20](https://tex.z-dn.net/?f=20x%2B40y%3D900%5C%5Cx%20%3D%2025-y%5C%5C20%2825-y%29%2B40y%3D900%5C%5C%5C%5C500-20y%2B40y%3D900%5C%5C500%2B20y%3D900%5C%5C20y%3D900-500%5C%5C20y%3D400%5C%5C%5Cfrac%7B20y%7D%7B20%7D%3D%5Cfrac%7B400%7D%7B20%7D%5C%5C%20y%3D20)
Let's substitute the value of y into equation(i)
![x+y =25\\x+20 = 25\\x = 25 - 20\\x = 5](https://tex.z-dn.net/?f=x%2By%20%3D25%5C%5Cx%2B20%20%3D%2025%5C%5Cx%20%3D%2025%20-%2020%5C%5Cx%20%3D%205)
From the calculations above, they rented 5 self-propelled mowers and 20 riding mowers.

hope it helps
Answer:
x = 59°
y = 67°
Step-by-step explanation:
x = y - 8
x + y + 54 = 180
(y - 8) + y = 180 - 54
2y - 8 = 126
2y = 134
y = 67°
x = 59°
Step-by-step explanation:
Area of a Rectangle = Length x Width
28 ft² = L x 5ft
28 ft² / 5ft = Length
5.6 ft = length. CHOICE A.
Perimeter of a Rectangle = 2(L + W)
20 ft = 2(L + 4)
20 ft = 2L + 8
20 - 8 = 2L
12 = 2L
12/2 = 2L/2
6 ft= Length CHOICE A.
