A newspaper reports the following changes in the temperature of a city over 4 days: 2.34 degrees Celsius, negative 2 over 7 degrees Celsius, −0.45 degrees Celsius, 3 over 8 degrees Celsius

Write an expression to show the average daily change in the temperature of the city.

Write the steps to solve the expression. Round your answer to the nearest hundredth

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:

a+b=c is your answer

the answer is d.x= 90°

y= 50°

arc lm= 100°
