Students are going on a field
trip. a total of 8 vehicles will be
needed for 80 students. each
bus holds 13 students and vans
hold 5 students. find how many
buses and vans were taken.

5 buses and 3 vans were taken.

Step-by-step explanation:

x+y=8

13x+5y=80

x=8-y

13(8-y)+5y=80

104-13y+5y=80

104-8y=80

8y=104-80

8y=24

y=24/8

y=3

x+3=8

x=8-3=5

x=5, y=3. (5, 3)

5 buses and 3 vans were taken.

an altitude of 15,000 feet

step-by-step explanation:

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
