Given:

Jamie and Marshall's team tied Shawna and Wyatt's team for the top team score.

Marshall scores 12 less than Jamie. Shawna scored twice as much as Marshall. Wyatt scored 4 less than Shawna.

To find:

The individual score of each person.

Solution:

Let x be the score of Jamie.

Marshall scores 12 less than Jamie.

Marshall score = x-12

Shawna scored twice as much as Marshall.

Shawna score = 2(x-12)

Wyatt scored 4 less than Shawna.

Wyatt score = 2(x-12)-4

Now,

Score of Jamie and Marshall's team $=x+(x-12)$

Score of Shawna and Wyatt's team $=2(x-12)+2(x-12)-4$

Jamie and Marshall's team tied Shawna and Wyatt's team

$x+(x-12)=2(x-12)+2(x-12)-4$

$x+x-12=2x-24+2x-24-4$

$2x-12=4x-52$

Isolate x.

$2x-4x=-52+12$

$-2x=-40$

Divide both sides by -2.

$x=\dfrac{-40}{-2}$

$x=20$

So, Jamie score = 20

Marshall score = 20-12

= 8

Shawna score = 2(20-12)

= 2(8)

= 16

Wyatt score = 2(20-12)-4

= 2(8)-4

= 16-4

= 12

Therefore, the scores of Jamie, Marshall, Shawna and Wyatt are 20, 8, 16 and 12 respectively.

The area of a rectangle is 14 m2 , and the length of the rectangle is 3 m less than double the width. find the dimensions of the

muminat

Width =3.5, length = 4

Let's make a few equations to summarize what we know.:
a = 14
l = 2w -3
a = wl

Now let's substitute the expression for l into the expression for area and solve.
a = w(2w - 3)
a = 2w^2 - 3w
14 = 2w^2 - 3w

0 = 2w^2 - 3w - 14

which factors into
(2w - 7) (w + 2)

Solving for w
2w - 7 = 0
2w = 7
w = 3.5

w+2 = 0
w = -2

So w can be either 3.5 or -2. Since a negative width doesn't make sense, w = 3.5

Let's verify
w = 3.5
l = 2w - 3
l = 2*3.5 - 3
l = 7 - 3
l = 4
a = wl
a = 3.5 * 4
a = 14

So the width is 3.5 and the length is 4.
