The length of a rectangle is two thirds its width. the area is 12 square meters. find its width. round your answer to two decima
ziro4ka [17]
L = ( \frac{2}{3} )w
a = 12 
Length times width = area 
L · w = a
( \frac{2}{3} )w · w = 12
( \frac{2}{3} ) w^{2} = 12
Divide both sides by \frac{2}{3} or mulitply both sides by \frac{3}{2} (either one is fine)
( \frac{2}{3} ) ÷ ( \frac{2}{3} ) w^{2} = 12 ÷ ( \frac{2}{3} )
or
( \frac{3}{2} ) ( \frac{2}{3} ) w^{2} = 12 ( \frac{3}{2} )
w^{2} = 18
Square root both sides to get rid of the squared on the w
\sqrt{w^{2} } = \sqrt{18}
w = 4.24

u should:

7t = t + 48 » 7t - t = 48 » 6t = 48 » t = 8

and another one is:

2u + t + 13 = 10t + u - 44» 2u + 8 + 13 = 80 + u - 44»
