Xavier is buying bottled water for his basketball team. If he has $20 to spend on water, and each bottle of water costs $1.50, write an expression for the amount of money he will

Step-by-step explanation:

1.5 * 13 = 19.5 dollars

0.50 = 20 - 1.5x   where 0.50 is the amount of money he has left and x is the number of bottles of water  he buys

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

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:
