Elena walked 20 minutes more than Lin. Jada walked twice as long as Elena. Jada walked for 90 minutes. The equation describes this situation. Match(x0)902+2=each amount in the story with the expression that represents it. Explain how you figured it out.

Explanation:

The question is partially garbled and incomplete.

Please, see the complete question in the picture attached.

Translate each verbal statement into an algebraic expression.

1. First statement: Elena walked 20 minutes more than Lin.

Use the time walked by Lin as your reference value and call it x, as it is unknown. Then:

2. Second statement: Jada walked twice as long as Elena:

3. Third statement: Jada walked 90 minutes.

This, lets you to set the equation (equality):

Now, you have all the terms and their meaning:

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:
