2) Solve the following equation for x: 2(x-5) = 36
A) 15.5 В) 23 С) 18
D) 13

i got C

Step-by-step explanation:

2(x-5)=36

divide both sides by 2

x-5=13

add 5 to both sides

x=18

the answer is 15% decrease

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:
