25: Rebecca has two dogs, Lucky and Pepe.
Lucky weighs 5.4 kilograms.
Pepe is 800 grams lighter than Lucky.
Work out how much Pepe weighs.
State your units.

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!!

step-by-step explan mxfcg'k; uafwgzfgjhklhgation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
