The sum of two numbers is 75. The second number is 3 less than twice the first

Mandarinka [93]

Answer:

$\large{\textbf{The two numbers are: 26 and 49}.\\}$

Step-by-step explanation:

$\large{\textup{assume the two numbers are $x$ and $y$.}}\\\large{\textup{The given sentences are written in mathematical terms as follows:}\\$$ x + y = 75 \hspace{25mm} (1)$$ $$ y = 2x - 3 \hspace{25mm} (2) $$ \\\textup{Substituting $(2)$ in $(1)$,}\\\begin{align*} & \implies x + 2x - 3 = 75 \\& \implies 3x = 78 \\& \implies x = 26\end{align*}\textup{Substituting $x$ in $(1), \hspace{5mm} y = 49$} }$

A number, half of that number, and one fifth of that number are added. The result is 51. What is the original number?

Lera25 [3.4K]

Let the original number be ‘x’
Then half of that number= 1/2x or simply x/2
Similarly one fifth of that number = x/5
According to the question
x+x/2+x/5=51
Taking LCM
10x/10+2x/10+5x/10=51
Multiplying 10 throughout
10x+2x+5x=510
17x=510
x=510/17
Therefore x=30

Some Quadratic functions <br>I desperately need some help

Daniel [21]

Answer:

$\large\boxed{0=3x^2+2x-2}\\\\\boxed{0=-3x+3x^2-2}\\\\\boxed{0=-1x-2+3x^2}$

Step-by-step explanation:

$\text{The quadratic equation:}\\\\ax^2+bx+c=0\\\\a-coefficient\\\\c-constant\ term\\\\\text{We have}\ coefficient\ a=3\ \text{and}\ constant\ term\ c=-2.\\\\\text{Therefore the equation is:}\\\\3x^2+bx-2=0\\3x^2-2+bx=0\\bx+3x^2-2=0\\bx-2+3x^2=0\\-2+3x^2+bx=0\\-2+bx+3x^2=0$
