Best ResponseYou've already chosen the best response.0I'm not familiar with these ratios. 16/4? Or 16 = 4?

Best ResponseYou've already chosen the best response.0Since they're similar, you can set up a proportion. Make sure you keep the same triangle in the same fraction and the same sides in the same spot (numerator or denominator). \[\frac{ x3 }{ 16 }=\frac{ 2.5 }{ 4 }\]Now, cross multiply:\[4(x3)=16(2.5)\]\[4x12=40\] Can you solve from here? :o)

Best ResponseYou've already chosen the best response.0\[4x  12 = 40\]\[4x = 40 + 12\]\[4x = 52\]\[4x / 4x = 52 / 4x\]\[x = 13\]
