The triangles below are similar find the value of x...help I’m stuck

Sergeu [11.5K]

Well, since it is multiple choice, you can just eliminate the answers. If you take 5/4 it equals 1.25. Then you go through the choices. All of the numbers, except 7.2 (C) are infinite. And, 7.2 gives you the 1.25 from before... which is your answer
If this helped, brainliest would be great! Only need one more to level up :)

a student played a computer game 500 times and won 370 of these game. he then won the next "x" games and lost none. he has now w

a_sh-v [17]

So, this is a proportion problem. If we express 75% as a fraction (3/4ths), we have:

$\frac{370+x}{500+x}=\frac{3}{4}$

Since he won all of his games, we add the number won (x), to the number previously won and divide it by the total games played which is just the previous games played plus the number of current games played, so since he lost no games we still add x to the denominator as well. Solving this gives us:

$4(370+x)=3(500+x) \implies\\ 1480+4x=1500+3x \implies \\ x=20$

That x value is 20.

solve for the indicated variable. include all of your work in your answer. submit your solution. P=2L+2W; for L.

allochka39001 [22]

We have this equation:

$P=2L+2W$

So, we need to solve this equation for L. Then we sum -2W in each member of the equation, like this:

$P-2W=2L+2W-2W$
$P-2W=2L$

Then, dividing the equation by 2:

$\frac{P-2W}{2}=L$

Finally, let's order this equation:

$L=\frac{P-2W}{2}$
