David's last equation to solve is x/100+3/100=8/100. Write and solve an equivalent equation with easier numbers that would give
JulijaS [17]
\sf\dfrac{x}{100}+\dfrac{3}{100}=\dfrac{8}{100}

Subtract 3/100 to both sides:

\sf\dfrac{x}{100}=\dfrac{5}{100}

Cross multiply:

\sf100x=500

Divide 100 to both sides:

\sf~x=5

Or we could just multiply both sides of the equation by 100, to give us:

\sf~x+3=8

Subtract 3 to both sides:

\sf~x=5

Find the volume of a rectangular prism with a height of 18 if the base has a length of 9 and a width of 17.
docker41 [41]

Hey there! I'm happy to help!

To find the volume of a rectangular prism, you simply multiply each of the three different sides!

18×9×17=2754

Therefore, the volume of this rectangular prism is c. 2754 units cubed.

Now you can find the volume of a rectangular prism! Have a wonderful day!

Y=17-5x/-9

You can’t go any further than that because you can’t combine unlike Terms on the right side of the equation.

How to show these 2 problems are inverses
nataly862011 [7]
\bf \begin{cases}
f(x)=\sqrt[3]{7x-2}\\\\
g(x)=\cfrac{x^3+2}{7}
\end{cases}\\\\
-----------------------------\\\\
now
\\\\
f[\ g(x)\ ]\implies f\left[ \frac{x^3+2}{7} \right]\implies \sqrt[3]{7\left[ \frac{x^3+2}{7} \right]-2}\implies \sqrt[3]{x^3+2-2}
\\\\\\
\sqrt[3]{x^3}\implies x\\\\
-----------------------------\\\\
or
\\\\
g[\ f(x)\ ]\implies g\left[\sqrt[3]{7x-2}\right]\implies \cfrac{\left[\sqrt[3]{7x-2}\right]^3+2}{7}
\\\\\\
\cfrac{7x-2+2}{7}\implies \cfrac{7x}{7}\implies x

thus f[ g(x) ] = x indeed, or g[ f(x) ] =x, thus they're indeed inverse of each other
