X=7. The two segments on the bottom as well as on the diagonal are the same length. This shows that the entire triangle and the inner triangle on the right are similar. So if we call the length of the bottom 2y, then 84/2y=6x/y. Solving this we get 84=12x, and so x=7

Paraphin [41]

Answer:

$x=-243$

Step-by-step explanation:

The equation is

$-3^{-5}=\frac{1}{x}$

Solve for x

we know that

$-3^{-5}=-\frac{1}{3^{5}}=-\frac{1}{243}$

substitute

$-\frac{1}{243}=\frac{1}{x}$

so

$x=-243$

Please help I'll give the brainiest to the right answer!

Anna [14]

Answer:

$x=1$

Step-by-step explanation:

Because vertical angles are always equal, we want to solve $50x+10=70x-10$ .

We can add 10 to both sides to get $50x+20=70x$ .

We can subtract $50x$ from both sides to get $20=20x$ .

Lastly, we divide both sides by 20 to get $1=x$ .

So, $\boxed{x=1}$ and we're done!

The check is left as an exercise to the reader.
