Answer:
x = 2/3
Step-by-step explanation:
2(x-2/3) = 0
2x - 4/3 = 0
2x = 4/3
x = 4/6 = 2/3
OR
2(x-2/3) = 0 (divide both sides by 2)
x-2/3 = 0
x = 2/3
Answer:
Selling price of the laptop is $600.
Step-by-step explanation:
Let the sale price of the laptop = $x
Regular price of the laptop = $750
Discount on each computer = 20%
Selling price of the laptop 'x' = 750 - (20% of 750)
= 750 - ![(\frac{20}{100}\times 750)](https://tex.z-dn.net/?f=%28%5Cfrac%7B20%7D%7B100%7D%5Ctimes%20750%29)
= 750 - 150
= $600
Therefore, selling price of the laptop is $600.
Answer:
The length is 24, width is 6
Step-by-step explanation:
Since we know the length and width cannot both be 12 (to make 144), other factors of 12 can be tested to be a product of 144. Half of 12 is 6, and 24 * 6 = 144. If we add up 12 + 12 + 6 + 6, we get 60, or the given perimeter.

Answer:
The question
after change the mixed number to improper & using KCF will become : ![\mathbf{=\frac{7}{2}\times \frac{3}{1}}](https://tex.z-dn.net/?f=%5Cmathbf%7B%3D%5Cfrac%7B7%7D%7B2%7D%5Ctimes%20%5Cfrac%7B3%7D%7B1%7D%7D)
Option B is correct option.
Step-by-step explanation:
We need to change the mixed number to improper & use KCF to rewrite the question.
The expression is: ![3\frac{1}{2}\div\frac{1}{3}](https://tex.z-dn.net/?f=3%5Cfrac%7B1%7D%7B2%7D%5Cdiv%5Cfrac%7B1%7D%7B3%7D)
First converting mixed fraction into improper fraction
Multiply whole number with the denominator i,e (3*2=6) now add the numerator i.e (6+1) = 7/2
Solving:
![3\frac{1}{2}\div\frac{1}{3}\\=\frac{7}{2}\div\frac{1}{3}](https://tex.z-dn.net/?f=3%5Cfrac%7B1%7D%7B2%7D%5Cdiv%5Cfrac%7B1%7D%7B3%7D%5C%5C%3D%5Cfrac%7B7%7D%7B2%7D%5Cdiv%5Cfrac%7B1%7D%7B3%7D)
Using KCF
KCF stands fro Keep it, Change it, Flip it.
It is used when division sign is converted to multiplication the term (1/3) is reversed to (3/1)
So, our expression will be
![=\frac{7}{2}\times \frac{3}{1}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B7%7D%7B2%7D%5Ctimes%20%5Cfrac%7B3%7D%7B1%7D)
So, The question
after change the mixed number to improper & using KCF will become : ![\mathbf{=\frac{7}{2}\times \frac{3}{1}}](https://tex.z-dn.net/?f=%5Cmathbf%7B%3D%5Cfrac%7B7%7D%7B2%7D%5Ctimes%20%5Cfrac%7B3%7D%7B1%7D%7D)
Option B is correct option.
