Airida [17]

Answer:

<h3>-3</h3>

Step-by-step explanation:

For two parallel lines. their slope are equal

Find the slope of each of the lines

For line A;

m = 0 -y/0+1

mA = -y/1

For line B;

mB = 9 - 3/8 - 6

mB = 6/2

mB = 3

since their slope are equal hence mA = mB

-y/1 = 3

-y = 3

y = -3

Hence the value of y is -3

Answer:

Pepe weighs 4600 grams.

Step-by-step explanation:

5.4 kilograms converted into grams is 5400 grams. Since Pepe is 800 grams lighter it would be 5400 - 800 which equals 4600 grams.

5.4 kilograms = 5400 grams

5400 - 800 = 4600

Hope this helps!!

Have an awesome day!!
