Answer:
$8.8
Step-by-step explanation:
Let the original price of shares be ![x](https://tex.z-dn.net/?f=x)
Profit earned = $1.320
percentage profit = 15%
∴ ![\frac{15x}{100} = 1.320\\15x = 132.0\\x = \frac{132}{15} \\x = 8.8](https://tex.z-dn.net/?f=%5Cfrac%7B15x%7D%7B100%7D%20%3D%201.320%5C%5C15x%20%3D%20132.0%5C%5Cx%20%3D%20%5Cfrac%7B132%7D%7B15%7D%20%5C%5Cx%20%3D%208.8)
Original price of shares were = $8.8
Answer:
![\boxed {\boxed {\sf x=0}}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%5Cboxed%20%7B%5Csf%20x%3D0%7D%7D)
Step-by-step explanation:
To solve this equation, we must isolate the variable (x) using inverse operations.
![-3(x-2)=6](https://tex.z-dn.net/?f=-3%28x-2%29%3D6)
x-2 is being multiplied by -3. The inverse operation of multiplication is division, so we divide both sides by -3.
![-3(x-2)/-3= 6/-3\\(x-2)=6 /-3 \\(x-2)= -2](https://tex.z-dn.net/?f=-3%28x-2%29%2F-3%3D%206%2F-3%5C%5C%28x-2%29%3D6%20%2F-3%20%5C%5C%28x-2%29%3D%20-2)
2 is being subtracted from x. The inverse operation of subtraction is addition, so add 2 to both sides of the equation.
![x-2+2=-2+2\\x=-2+2\\x=0](https://tex.z-dn.net/?f=x-2%2B2%3D-2%2B2%5C%5Cx%3D-2%2B2%5C%5Cx%3D0)
In this equation, x is equal to 0.
4 people would be in each row of there were 7 rows
Area=length times width ...so 10x5= 50..so 50cm sq is the answer :)
