Important need asap due today! will give brainliest answer i am sorry for making this one post but i'm in school i don't have time to make several 1.at the liberty school, 168 students- or 56% of the total student body-- are taking a foreign language course. how many students does liberty school have in all? 2.last year at state driver's license office, 16% of all the drivers seeking to renew their licenses had let their old licenses expire. in all, 23,400 people renewed licenses at this office. how many of their licenses had expired? 3.the park near the museum has a brick wall around it. the north wall of the park contains 6,230 bricks, which is only 70% of the bricks in the west wall. how many bricks does the west wall contain?

I have the answers for 1 and 2 but not 3.
1) Set up a proportion.
56/100 = 168/x
Use cross multiplication and division to solve for x: 168 X 100 = 16800 / 56, x=300

2) Set up proportion.
16/100 = 23400/x
Use cross multiplication and division to solve for x: 23400 X 100 = 2340000 / 16, x=146250

1.) 300 students

To find this you have to multiply the total number of students, x, by .56, the percent of sudents taking a foreign language class, and then set it equal to the number of students taking the class, 168, and solve.

.56x = 168

Divide each side by .56

x = 3

Multiply this by 100

300 students.

2.) 3,744 licenses were expired

To find this multiply 23,400 by .16 to find out how many licences expired.

23400(.16)

3,744 licenses were expired

3.) 2,670 bricks

To find this you have to multiply 6230 by .7 to find the number of bricks total, then subtract 6230 from that number to find the number of bricks in the west wall.

(6230/.7)-6230

8900-6230

2670 bricks in the west wall.

1.) 300 students
2.) 3,744 licenses were expired
3.) 2,670 bricks

Hope this helps!
