The perimeter of a rectangular garden is 44 meters. The length of the rectangle is 5 less than twice the width. Find the length
defon

9514 1404 393

Answer:

  • width: 9 m
  • length: 13 m

Step-by-step explanation:

Let w represent the width. Then the length is 2w-5, and the perimeter is ...

  P = 2(L+W)

  44 = 2((2w-5) +w)

  44 = 6w -10

  54 = 6w

  9 = w

  2(9) -5 = 13 = length

The length of the rectangle is 13 meters; the width is 9 meters.

Which value, when placed in the box, would result in a system of equations with infinitly many solutions? Y=2x - 5 2y-4x=
Nezavi [6.7K]

Given:

The system of equations is

y=2x-5

2y-4x=?

To find:

The missing value for which the given system of equations have infinitely many solutions.

Solution:

Let the missing value be k.

We have,

y=2x-5

2y-4x=k

Taking all the terms on the left side, the given equations can be rewritten as

-2x+y+5=0

-4x+2y-k=0

The system of equations a_1x+b_1y+c_1=0 and a_2x+b_2y+c_2=0 have infinitely many solutions if

\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}

We have,

a_1=-2,b_1=1,c_1=5

a_2=-4,b_2=2,c_2=-k

Now,

\dfrac{-2}{-4}=\dfrac{1}{2}=\dfrac{5}{-k}

\dfrac{1}{2}=\dfrac{1}{2}=\dfrac{5}{-k}

\dfrac{1}{2}=\dfrac{5}{-k}

On cross multiplication, we get

-k=10

k=-10

Therefore, the missing value is -10.

Answer:

\large\boxed{\sum\limits_{n=1}^5(-2.2+8.8n)}

Step-by-step explanation:

6.6,\ 15.4,\ 24.2,\ ...\\\\\text{It's an arithmetic sequence:}\\\\15.4-6.6=8.8\\24.2-15.4=8.8\\\\\text{The difference is constant.}\\\\\text{The explicit formula of an arithmetic sequence:}\\\\a_n=a_1+(n-1)d\\\\\text{Substitute:}\\\\a_1=6.6\ \text{and}\ d=8.8\\\\a_n=6.6+(n-1)(8.8)=6.6+8.8n-8.8=8.8n-2.2\\\\\text{Therefore}\\\\\sum\limits_{n=1}^5(8.8n-2.2)
