Answer:

X=-4 Y= 5

Step-by-step explanation:

solving the equation simultaneously

4X+7Y = 19-------------(1)

Y- X = 9-------------(2)

from equation (2),

Y = 9+X ----------------(3)

substituting equation (3) into equation (2)

4X+7(9+X)=19

removing bracket

4X+63+7X= 19

11x = 19-63

11X = -44

X= -44/11

X= -4

put X equal- 4 into equation (3)

Y= 9+-4

Y= 5

therefore, X= -4 Y = 5

therefore,

<h2>for the system of linear equation to be true, x must be= -4 and Y = 5</h2>

A circular swimming pool has a radius of 15 ft. There is a path all the way around that pool that is three feet wide. A circle h
LuckyWell [14K]

The circumference of the outer edge of the path around the pool is 113.04 ft.

<h3>What is the circumference?</h3>

The Circumference (or) perimeter of circle = 2πR. where, R is the radius of the circle.

Given

A circular swimming pool has a radius of 15 ft.

There is a path all the way around that pool that is three feet wide.

A circle has a radius of 15 feet.

A larger circle goes around the smaller circle that is 3 feet wide.

The radius of the outer edge of the path around the pool = Radius of circle + width of outer circle.

The radius of the outer edge of the path around the pool = 15 + 3

The radius of the outer edge of the path around the pool = 18ft

The circumference of the outer edge of the path around the pool is;

\rm Circumference=2\pi r\\\\Circumference = 2\times 3.14 \times 18\\\\Circumference=113.04 \ ft

Hence, the circumference of the outer edge of the path around the pool is 113.04 ft.
