Answer:
i don't what you want me to do here...
You gave me the same problem just two different numbers so maybe the answer is 7... idek tho bro
k times x = 7
k times x = 49
Step-by-step explanation:
A) 1.75p + 12 = 54
1.75p = 42
p = 24 bags
b) 1.75(70) + 12 = b
122.5 + 12 = b
b = $134.50
Tony’s backpack can carry weight up to 22 but not more that that
If the variable n represents the total weight carried by tony
Then ; n less than or equal to (n=1+3+3b
=4+3b
Where b represents book
4+3b is less or equal to 22
3b is less or equal to 18
b is less or equal to 6
Therefore Tony’s backpack cannot carry more than 6 books
If the 8y/4 is the only fraction, the answer is x=7y
If the whole input of the equation is in a fraction, the answer is x=28y

Answer:
The value of x is:
![x=\dfrac{5\pm \sqrt{103}i}{8}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B5%5Cpm%20%5Csqrt%7B103%7Di%7D%7B8%7D)
Step-by-step explanation:
we have to use the quadratic formula to solve for x.
The equation is given as:
![4x^2-3x+9=2x+1](https://tex.z-dn.net/?f=4x%5E2-3x%2B9%3D2x%2B1)
which could also be written as:
![4x^2-3x+9-2x-1=0\\\\4x^2-3x-2x+9-1=0\\\\\\4x^2-5x+8=0](https://tex.z-dn.net/?f=4x%5E2-3x%2B9-2x-1%3D0%5C%5C%5C%5C4x%5E2-3x-2x%2B9-1%3D0%5C%5C%5C%5C%5C%5C4x%5E2-5x%2B8%3D0)
The quadratic formula for the quadratic equation of the type:
is given as:
![x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B-b%5Cpm%20%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
Here we have:
a=4, b=-5 and c=8.
Hence, by the quadratic formula we have:
![x=\dfrac{-(-5)\pm \sqrt{(-5)^2-4\times 8\times 4}}{2\times 4}\\\\x=\dfrac{5\pm \sqrt{25-128}}{8}\\\\\\x=\dfrac{5\pm \sqrt{103}i}{8}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B-%28-5%29%5Cpm%20%5Csqrt%7B%28-5%29%5E2-4%5Ctimes%208%5Ctimes%204%7D%7D%7B2%5Ctimes%204%7D%5C%5C%5C%5Cx%3D%5Cdfrac%7B5%5Cpm%20%5Csqrt%7B25-128%7D%7D%7B8%7D%5C%5C%5C%5C%5C%5Cx%3D%5Cdfrac%7B5%5Cpm%20%5Csqrt%7B103%7Di%7D%7B8%7D)
Hence, the value of x is:
![x=\dfrac{5\pm \sqrt{103}i}{8}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B5%5Cpm%20%5Csqrt%7B103%7Di%7D%7B8%7D)
