Let's translate each sentence into "Math".
Pineapple = p
Orange = x
is means equal
Pineapple is 7 times as heavy as an orange: p = 7x
Pineapple weighs 870 grams more than orange. p = 870 + x
Substitute p = 7x into the second equation:
7x = 870 + x
Subtract x from both sides
6x = 870
divide by 6
x = 145
The orange weighs 145 grams.
The pineapple weights 7 times the orange = 7(145) = 1015 grams.

8 + 5 (x - 3)^3...when x = 9
8 + 5 (9 - 3)^3 =
8 + 5 (6^3) =
8 + 5(216) =
8 + 1080 =
1088
Answer:
D) 9
Step-by-step explanation:
Using proportions, we have
12/2 = 54/x
Cross multiplying, we have
12(x) = 2(54)
12x = 108
Divide both sides by 12:
12x/12 = 108/12
x = 9
