Answer:

1160 g, 1.16 kg

Step-by-step explanation:

System of equations:

p = 7o

p = o + 870

Plugging in 70 for p, we get:

7o = o + 870

6o = 870

o = 145

Now plugging in 145 for o into the first equation, we get:

p = 7(145)

p = 1015.

The total weight of the pineapple and orange in grams is 145 + 1015 = 1160 grams.

We can divide 1160 by 1000 to get the total amount of kilograms which is equal to 1160/1000 = 1.16 kilograms.
