Answer:

if it's finding x

#1 x<-1

#2 x<4

Step-by-step explanation:

2x-16<-18

add 16 to both sides

2x<-2

then divide 2 to both sides

x<-1

2x-16+4x<8

add like terms

6x-16+<8

add sixteen to both sides

6x<24

divide six to both sides

x<4

2) The two rectangles shown are similar.

Citrus2011 [14]

Answer:

$6\ cm$

Step-by-step explanation:

First Rectangle:

$length(l_1)=24\ cm\\\\Width(b_1)=9\ cm$

Second Rectangle:

$length(l_2)=16\ cm\\\\Let\ Width=b_2\ cm$

$Since\ these\ two\ rectangles\ are\ similar\\\\\frac{l_2}{l_1}=\frac{b_2}{b_1}\\\\\frac{16}{24}=\frac{b_2}{9}\\\\16\times 9=24\times b_2\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ cross\ multiplication\\\\b_2=\frac{16\times 9}{24}\\\\b_2=6\ cm$
