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.
