Who knows how to do this I TRULY NEED HELP

zavuch27 [327]

Answer:

x = 10

Step-by-step explanation:

It's given in the question that both the traingles JCD & JKL are similar. So their ratio of corresponding similar sides will be proportional to each other.

$= > \frac{JD}{JL} = \frac{JC}{JK} = \frac{DC}{LK}$

$= > \frac{15}{50} = \frac{8 + x}{60} = \frac{DC}{LK}$

$= > \frac{15}{50} = \frac{8 + x}{60}$

$= > 8 + x = \frac{15 \times 60}{50} = 18$

$= > x = 18 - 8 = 10$

Alex wrote the expanded form for the number 165.038 as 100+60+5+30+8. Was he correct? If not give expanded form.

oksano4ka [1.4K]

We have the next number

$165038$

The expanded form of the number is

$100000+60000+5000+30+8$

Also, we can verify that Alex was incorrect because if we do the sum of the expanded form that Alex calculated we obtain

$\begin{gathered} 100+60+5+30+8=203 \\ \text{And }203\ne165038 \end{gathered}$

Finally, the correct answer is

$100000+60000+5000+30+8$

Orlov [11]

Subtract what they already have from what they needed:

895 - 351 = 544

They need$544 more.

Divide how much more they need by the number of teams:

544/34 = 16

They need to charge each team $16
