A 70-meter path surrounds a rectangular garden. The width of the garden is two-thirds its length. Find the length and the width.

1 answer:

7 0

$width=\frac{2}{3}length\\\\
70=2width+2length\\\\
70=2length+2(\frac{2}{3}length)\\\\
70=2length+\frac{4}{3}length\\\\
70=\frac{10}{3}length\ \ | divide\ by\ \frac{10}{3}\\\\
70*\frac{3}{10}=length\\\\
length=21m\\\\
width=\frac{2}{3}*21=14m

Answer:

x = 47

Step-by-step explanation:

So It most likely adds up to 180 degrees so.

x + 10 + x -10 + x - 10 + x + 6 = 180 (collect like terms)

4x -4 = 184 ( add 4 on both sides)

4x = 188 (divide 188 by 4)

x = 47

47 + 10 = 57 ----> x + 10

47 - 10 = 37 -----> x - 10

47 + 6 = 53 ------> x + 6

Use matrix inversion to solve the collection of systems of linear equations. HINT [See Example 4.] (a) −x − 4y + 2z = −10 x + 2y

omeli [17]

Answer:

Step-by-step explanation:

given is a system of linear equations in 3 variables as

$-x - 4y + 2z = −10\\ x + 2y - z = 11 \\x + y - z = 14$

This can be represented in matrix form as

AX=B Or

$\left[\begin{array}{ccc}-1&-4&2\\1&2&-1\\1&1&-1\end{array}\right] *\left[\begin{array}{ccc}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}-10\\11\\14\end{array}\right]$

So solution set

X would be $A^{-1} B$

|A|=-1(-1)+4(0)+2(-1)=--1

Cofactors of A are

-1 0 -1

-2 -1 -3

0 1 2

So inverse of A is

1 2 0

0 1 -1

1 3 -2

Solution set would be

x=12

y=-3

z=-5
