m∠6 = 42°     m∠7 = 138

Step-by-step explanation:

Since we have the measure of angle 4, using the rule of verticle opposites, this means that the opposites are the same. so 4 = 2, and 6 = 8, and 1 = 3, and 5 = 7.

And since there is also the rule of same side correspondence, this means 4 = 8, and 6 = 2.

This means that since 4 = 42°, and 4 = 2, and 2 = 6, then m∠6 = 42°

and since 7 is opposite of 6 on a straight line, you can subtract 42 from 180 degrees to get the degree of 7.

180 - 42 = 138

so m∠7 = 138°

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:
