Aproduce store sold 63red apples .if the ratio of red apples to green apples was 7: 2 what is the combined amount of red and green apples sold?

 81 total apples were sold.

Step-by-step explanation:

63 : x green apples

7 : 2

63/7 = 9

9 * 7 = 63

9 * 2 = 18

x = 18

18 + 63 = 81

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
