S = (3, 5 )

Step-by-step explanation:

Given the endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ (x₁ + x₂ ), (y₁ + y₂ ) ]

let the coordinates of S be (x, y ), then using the midpoint formula equate the parts to the coordinates of the midpoint M

x = (x + 5) = 4 ( multiply both sides by 2 )

x + 5 = 8 ( subtract 5 from both sides )

x = 3

y = (y + 3) = 4 ( multiply both sides by 2 )

y + 3 = 8 ( subtract 3 from both sides )

y = 5

The coordinates of S = (3, 5 )

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
