Answer:
1060 grams
Step-by-step explanation:
let the weight of the orange be x, then
pineapple weighs 7x, and also x + 870
equating the 2 expressions for the weight of the pineapple
7x = x + 870 ( subtract x from both sides )
6x = 870 ( divide both sides by 6 )
x = 145
The orange weighs 145 grams and the pineapple 145 + 870 = 1015 grams
Total weight of both = 145 + 1015 = 1060 grams
