The width of a rectangle is 2 m less than one-third of the length x. The area is 144 m^2.

tresset_1 [31]

Answer:

L=18, W=8

Step-by-step explanation:

Given :

Area (A)=144 $m^2$ =LW

Where, L is length and W is width

According to given question ,

$W=\frac{1}{3} L-2$

Now,

A=LW

144=L $(\frac{1}{3} L-2)$

432= $L^{2} -6L$

$L^{2} -6L-432=0\\L^{2} -18L+24L-432\\(L+24) (L-18)\\L=-24\\and L=18$

Length can be in negative so L =18

And

$LW=144\\18W=144\\W=\frac{144}{18} \\W=8$

Therefore, Length of rectangle is 18 and Width is 8

For a school fund raising project, Aiden and Jacob collected money in the ratio of 3.5 : 6.8. Jacob collected $115.50 more than

user100 [1]

X - the amount of money collected by Aiden
y - the amount of money collected by Jacob

Aiden and Jacob collected money in the ratio of 3.5 : 6.8.
$\frac{x}{y}=\frac{3.5}{6.8} \\
6.8x=3.5y \\
x=\frac{3.5}{6.8}y \\ x=\frac{35}{68}y$

Jacob collected $115.50 more than Aiden.
$x+115.5=y \\
x=y-115.5 \\ \\
x=x \\
\frac{35}{68}y=y-115.5 \\
\frac{35}{68}y-y=-115.5 \\
\frac{35}{68}y-\frac{68}{68}y=-115.5 \\
-\frac{33}{68}y=-115.5 \\
y=-115.5 \times (-\frac{68}{33}) \\
y=238 \\ \\
x=y-115.5=238-115.5=122.5 \\ \\
x+y=238+122.5=360.5$

The total amount of money they collected is $360.50.
