Answer with detail -17= -3 - 2n 54= 17n- (-3)

We need to find the value of n in the first equation, so you would do:

- 17 = -3 - 2n

Add 3 to both sides to cancel the -3 in the side of the n variable

- 14 = -2n

Next divide to get rid of the -2 because it is multiplied by the -2

7 = n

54 = 17n - (-3)

Since you know that a negative times a negative transforms into a positive this is what it would look like:

54 = 17n + 3

Subtract 3

51 = 17n

Divide by 17 and n would be

n = 3

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

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:
