Area of 5 = {(4x+3)×(2x+3-x-2)}+{(x+2)×(x+1)}

={(4x+3)×(x+1)}+{(x+2)×(x+1)}

Area of 6 = {(3x+8)×(3x+5-x-3)}+{(x+3)×(x+3)}

= {(3x+8)×(2x+2)}+{(x+3)×(x+3)

Write a scenario that could be represented by this equation: 3/4x = 12

Aneli [31]

Answer:

x=1 or x=16

Step-by-step explanation:

3/4x = 12 or 0.75x = 12

3/4x/3/4 = 12/3/4 or 0.75x/0.75 = 12/0.75

x=12/1 / 3/4

x= 4/4

x = 1 or x = 16

tangare [24]

$\\
\text{Let Manas receives a commission of Rs. 5000 on sales of Rs. 65000}\\
\\
\text{We need to find how much commision he will get on the sale of Rs.20000}\\
\\
\text{To find the commision, we use the unitary method.}\\
\\
\text{On sales of Rs. 65000, Manas receives a commision of}=5000\\
\\
\text{so on sales of Rs. 1, Manas will receiv a commision of}=\frac{5000}{65000}\\
\\
\text{Hence on sales of Rs. 20000, Manas will receiv a commision of}\\
\\=\frac{5000}{65000}\times 20000\\
\\
=1538.46$
