What is the value of y?
A) 40
B) 60
C)70
D)80

B, 60 degrees

Step-by-step explanation:

The sum of all angle measurements in a triangle is 180 degrees. Since all of the angles in this triangle are the same measurement, you can divide 180 evenly among the three angles (one of which is y). 180/3 = 60.

Therefore, y = 60.

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your 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:
