a pineapple is 7 times as heavy as an orange. the pineapple also weight 870 grams more than orange what is the total weight in g
rams for the pineapple and orange
1 answer:
Let's call p= pineapple weight
and. g=orange weight
we have p=7*g
and. p=g+870
replacing the the second equation in the first we have
g+870=7*g
that means 870 = 7*g - g
870 = 6*g
g = 870/6 = 145
and p = 7*g = 1015
