Solve for x with a step by step explanation please<br> (3/5)x+1/4=(3/4)x-2/5

11111nata11111 [884]

Answer:

$\frac{3 \times 4}{5 \times 4} x - \frac{3 \times 5}{4 \times 5} x = - \frac{2 \times 4}{5 \times 4} - \frac{1 \times 4}{5 \times 4}$

$\frac{12x - 15x}{20} = \frac{ - 8 - 4}{20}$

/·20

12x-15x = -8-4

-3x= -12. /·(-1)

3x=12

x=4

Step-by-step explanation:

$\frac{3}{5} x - \frac{3}{4} x = - \frac{2}{5} - \frac{1}{4}$

Answer:

$volume = 10m^3$

Step-by-step explanation:

This shape is called a rectangular prism. The formula for finding the volume of this prism is: $volume = L * W * H$

All you do is plug the values into the formula.

The length is 2m

The width is 1m

the height is 5m

Volume = (2m)(1m)(5m)

Volume = $10m^3$

Find a fraction equivalent to 5/7 whose squared terms add up to 1184.

bogdanovich [222]

The system of equations of two unknowns is formulated and solved.

$\large\displaystyle\text{$\begin{gathered}\sf \bf{ \left\{\begin{matrix} \ \ \ \dfrac{x}{y} = \dfrac{5}{7} \\ x^2+y^2 = 1184 \end{matrix}\right. \ \Longrightarrow \ x=\dfrac{5}{7}y } \end{gathered}$}$

$\large\displaystyle\text{$\begin{gathered}\sf \bf{ \left (\dfrac{5}{7}y \right )^2+y^2=1184\ \Longrightarrow\ 25y^2+49y^2=58016 } \end{gathered}$}$

$\large\displaystyle\text{$\begin{gathered}\sf \bf{74y^{2}=58016} \end{gathered}$}\\\large\displaystyle\text{$\begin{gathered}\sf \bf{ \ \ \ \ \ \ y^{2}=784 } \end{gathered}$}\\\large\displaystyle\text{$\begin{gathered}\sf \bf{ \ \ \ \ \ y=\pm\sqrt{784}=\pm28 } \end{gathered}$}$

$\large\displaystyle\text{$\begin{gathered}\sf \bf{ x=\dfrac{5}{7}(\pm 28)=\pm 20 } \end{gathered}$}$

The fraction that satisfies the request is $\bf{\dfrac{20}{28}}$ , since in $\bf{\dfrac{-20}{-28}}$ the negative signs are canceled and the first fraction is obtained.
