Step-by-step explanation:
Build a rectangle 12 cm high and 5 cm wide (Paint it). Then a) Find the perimeter of the rectangle. B) Find the area of the rectangle. Aiuda porfis.
Length of the rectangle is 12 cm
Breadth of the rectangle is 5 cm
Perimeter is the sum of all sides. For rectangle it is given by :
P = 2(l+b)
⇒ P=2(12+5)
P = 34 cm
Area of a rectangle is equal to the product of its length and breadth.
So,
A = lb
A = 12 cm × 5 cm
⇒A = 60 cm²
Hence, perimeter is 34 cm and area of rectangle is 60 cm².
Answer:
y= 15
Step-by-step explanation:
-25+ 4y = 35
+25 +25
4y = 60
y= 60/4
y= 15
Answer:
B. 13 small bags and 12 large bags
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the number of small bags.
y is the number of large bags.
The Tuesday morning delivery consists of 25 bags
This means that
, that is ![y = 25 - x](https://tex.z-dn.net/?f=y%20%3D%2025%20-%20x)
Bunyan Farm sells 3 pound and 5 pound bags of onions. Total of 99 pounds.
This means that ![3x + 5y = 99](https://tex.z-dn.net/?f=3x%20%2B%205y%20%3D%2099)
Since ![y = 25 - x](https://tex.z-dn.net/?f=y%20%3D%2025%20-%20x)
![3x + 5(25 - x) = 99](https://tex.z-dn.net/?f=3x%20%2B%205%2825%20-%20x%29%20%3D%2099)
![3x + 125 - 5x = 99](https://tex.z-dn.net/?f=3x%20%2B%20125%20-%205x%20%3D%2099)
![-2x = -26](https://tex.z-dn.net/?f=-2x%20%3D%20-26)
![2x = 26](https://tex.z-dn.net/?f=2x%20%3D%2026)
![x = \frac{26}{2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B26%7D%7B2%7D)
![x = 13](https://tex.z-dn.net/?f=x%20%3D%2013)
![y = 25 - x = 25 - 13 = 12](https://tex.z-dn.net/?f=y%20%3D%2025%20-%20x%20%3D%2025%20-%2013%20%3D%2012)
So 13 small bags and 12 large bags.
