What is the midpoint of the line segment with endpoints (-5.5, -6.1) and (-0.5,9.1)? options: a: (-3, 1.5) b: (-6, 3) c: (-6, 1.5) d: (-3, 3)

A: (-3, 1.5)

Step-by-step explanation:

((-5.5, -6.1) + (-0.5, 9.1))/2 = (-6, 3)/2 = (-3, 1.5)

The midpoint coordinates are the average of the two end point coordinates. Add them up and divide by 2.

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:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
