One market sells a 3 kilogram bag of tortillas for 42 pesos and another sells 2 kilograms of tortillas for 26 pesos which unit p
Dafna1 [17]

Answer:

2 kilogram bag.

Step-by-step explanation:

To figure this out, we need to divide the price by the amount of kilograms. Lets start with the 3 kilo bag. Divide 42 by 3, let y equal the price per kilo

42/3=y

Divide

14=y

Now lets do the same with the 2 kilo bag. Divide 26 by 2. Let x be this number.

26/2=x

divide

13=x

The 2 kilo bag is better as its 13 pesos per kilo compared to the 3 kilo bag's 14 pesos per kilogram.

URGENT 25 PTS IF ANSWERED PLEASE HELP
dangina [55]

Answer:

b. x= -6 or x=2

Step-by-step explanation:

|2x+ 4| = 8

The absolute value equation has 2 solutions, one positive and one negative

2x+4 = 8           2x+4 = -8

Subtract 4 from each side

2x+4-4 = 8-4      2x+4-4 = -8-4

2x = 4                  2x = -12

2x/2 =4/2              2x/2 = -12/2

x =2                      x = -6
