Mathematics
1 answer:
almond37 [142]2 years ago
7 0

Answer:

(D) 30

Step-by-step explanation:

number of green marbles = x

number of red marbles = 5

total number of marbles = x + 5

p(red) = (number of red marbles)/(total number of marbles)

p(red) = 5/(x + 5)

p(red) = 1/7

5/(x + 5) = 1/7

(x + 5) × 1 = 5 × 7

x + 5 = 35

x = 30

Answer: (D) 30
