With this equation! i need an answer soon! you! (picture is below)

15,75,90

Step-by-step explanation:

the 2 acute angles of a right triangle add to 90 degrees

the other angle is a right angle which equals 90 degrees

lets call them x and y

x = 5y  one is 5 times the other

x+y = 90

substitute x=5y

5y+y =90

combine like terms

6y =90

divide each side by 6

y = 90/6

y = 15

x = 5*y

x = 5*15

x = 75

the three angles are x, y, right angle

75, 15, 90

put them in order from smallest to largest

15,75,90

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

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:
