1.Your answer is right,
Solution:
let n be the price of the ride on a zip line of 12 friends
3:12=750/n
3/12=750/n
3n=750×12
3n=9000
3 3
n=3000
2. Your answer is correct again,here is the solution:
x=3:(1:2:3)
x=3/(1+2+3)
x=3/6
x=1/2
=1/2(1)
=1/2
3. Your answer is correct again
x=200:(1:4:5)
x=200/(1+4+5)
x=200/10
x=20
Proving:
=20(1)+20(4)+20(5)
=20+80+100
=400
4. Your answer is correct again
1680:3=n:8
1680/3=n/8
3n=1680×8
3n=13440
3 3
n=4480
5. Let n be the time that Kyla take to reach grandma's house
60×24=40n
1440=40n
