Similar triangles so AC:BC=AE:DE

15+6=21 = AE

15:12.5=21:?

to get from 15 to 12.5 you divide by 15 and times by 12.5 so do this the to the other side

21/15=1.4

1.4 x 12.5=17.5

So DE=17.5

Find for x<br><br> 1/5x + 1/3= 3(2/3x -2)
topjm [15]

Answer:

The value of x  for the given expression is  (95/27)

Step-by-step explanation:

Here, the given expression is:

\frac{1}{5} x + \frac{1}{3}   = 3(\frac{2}{3}x -2)

Now here  solving for the value of x , we get

\frac{1}{5} x + \frac{1}{3}   = 3(\frac{2}{3}x) -6\\\implies\frac{1}{5} x + \frac{1}{3}   = 2x -6

Now, taking the variable terms on 1 side, we get

\frac{1}{5} x   - 2x   = -6 -  \frac{1}{3} \\\implies\frac{x  - 10x}{5}   = -(\frac{6(3)  +1}{3} )

or, \frac{-9x}{5}   = -\frac{19}{3}   \implies x  = \frac{19}{3}  \times\frac{5}{9}   = \frac{95}{27}

Hence,  the value of x = (95/27)

In the figure, quadrilateral ABCD≅≅ quadrilateral LMNO. Find m. Only type the numerical amount.
Talja [164]
Using our congruence statement ABCD \cong LMNO, we know that corresponding angles match, so that means that \angle M \cong \angle B.  We know that m \angle B=131, so that means that m \angle M=131.  This gives us the equation 
<em /><em /><em>m</em> + 45 = 131
Subtract 45 from both sides to cancel it and we have 
<em>m</em> = 86.
