I’m confused can anyone break this down to me

2.99 inches

Step-by-step explanation:

When two objects are proportional, this means that if the side length of one is greater than the respective side length of the other by a certain number, then all of the other respective sides will also be larger by that amount. 6.21 is 1.15 times larger than 5.4, and so the width of the second phone will also be 1.15 times larger than the width of the first phone, which was 2.5. 2.5 * 1.15=2.99 in. Hope this helps!

Step-by-step explanation:

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:
