The number of men in a tour group is 15 times the number of women. if there are 48 people in the group, how many are men?

45

Step-by-step explanation:

Given : The number of men in a tour group is 15 times the number of women.

To Find: If there are 48 people in the group, how many are men?

Solution:

Let the number of women be x

Now we are given that number of men in a tour group is 15 times the number of women.

So, no. of men = 15x

Now we are given that there are 48 people .

So,

Thus number of women = 3

Number of men =

Hence there are 45 men.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
