Answer: y = 6

Step-by-step explanation:

The small triangle MNO is similar to the big triangle LNP, which means their sides are proportional

$\text{Small}\triangle \quad \text{Big}\triangle \\\\\\\dfrac{MN}{ON}=\dfrac{LN}{PN}\\\\\\\dfrac{24}{y}=\dfrac{9+24}{6+y}\\\\\\24(6+y)=y(9+24)\\144+24y=33y\\\\144=9y\\\\\large\boxed{16=y}$

Step-by-step explanation: (I'm not gonna' do it all for you tho)

to convert from percent to fraction:

70% = $\frac{70}{100} =\frac{7}{10}$

to convert from fraction to percent:

$\frac{11}{20}=\frac{55}{100}$ = 55%

to convert from fraction to decimal:

$\frac{3}{25} =\frac{12}{100} =0.12$

to convert from decimal to fraction:

$1.25=\frac{125}{100} =1\frac{25}{100} =1\frac{1}{4}$

to convert from percent to decimal:

0.2% = $\frac{0.2}{100} =0.002$

to convert from decimal to percent:

$0.4= (0.4*100)$ % = 40%

With that, you can solve the rest on your own
