Sylvia buys a case of water that contains 24 bottles and sells x number of bottles to her co-workers. Sam buys a case of water t
zzz [600]

Answer:

6

Step-by-step explanation:

Number of water bottles bought by Sylvia = 24

Number of water bottles sold by Sylvia = x

Number of water bottles left with Sylvia = 24-x

Number of water bottles bought by Sam = 36

Number of water bottles sold by Sam = Three times as many as bottles as Sylvia sold = 3x

Number of water bottles left with Sam = 36-3x

It is given that the number of water bottles left with Sylvia and Sam are equal.

i.e.

24-x=36-3x\\\Rightarrow 2x=12\\\Rightarrow x =\bold{6}

So, number of water bottles sold by Sylvia = <em>6</em>

∆JKL~∆MNO and J/K MN =2/3 find the length of NO if KL=12.
Gre4nikov [31]

Answer:

Therefore the length of NO is 18 units.

Step-by-step explanation:

Given:

∆JKL~∆MNO and

\dfrac{JK}{MN}=\dfrac{2}{3}

KL = 12.

To Find :

the length of NO = ?

Solution:

Δ JKL ~ Δ LMN ….{Given)

If two triangles are similar then their sides are in proportion.  

\dfrac{JK}{MN} =\dfrac{KL}{NO}=\dfrac{JL}{MO} \textrm{corresponding sides of similar triangles are in proportion}\\  

Substituting the values we get

\dfrac{2}{3} =\dfrac{12}{NO}\\\\NO=\dfrac{36}{2}=18\\\\NO=18\ unit

Therefore the length of NO is 18 units.
