Korolek [52]

Answer:

Part A) The system of equations is equal to

$41=4x+7y$

$33=(3x+7y)$

Part B)

The length is $24\ in$

The width is $9\ in$

Step-by-step explanation:

Part A)

we know that

The perimeter of the triangle is equal to the sum of the length of its three sides

In this problem

$41=x+3x+7y$

$41=4x+7y$ -----> equation A

The perimeter of rectangle is equal to

$P=2(L+W)$

In this problem

$66=2(3x+7y)$

$33=(3x+7y)$ ------> equation B

Part B)

Using a graphing tool

Solve the system of equations

We know that

The intersection point both graphs is the solution of the system of equations

$41=4x+7y$

$33=(3x+7y)$

The intersection point is $(8,9/7)$

see the attached figure

$x=8\ in$

$y=(9/7)\ in$

step 3

Find the length and width of the rectangle

The length is 3x

$3*8=24\ in$

The width is 7y

$7*(9/7)=9\ in$

ZanzabumX [31]

8 1-and-a-half blocks would be 12 blocks, and so 12/17, because 12 blocks in 17 mins., so you divide 12 by 17 to get ---- blocks per minute, which is 12/17 as a fraction, or approx. 0.705882353 blocks per minute.
