Answer:
13
Step-by-step explanation:
13 because there pretend there is 24 people then it would be 12 but then there is one left over so 13 because somebody would have to shake hands with that person
To do this problem, you need to use the Pythagorean thermion I think.
Here is what I got as an answer
22.5 km
Here is the graph with your line in it.
9.08+x=25.08
-9.08 -9.08
x=16
3/4x=12
x4/3 x4/3
x=16
4.5x=72
/4.5 /4.5
x=16
Both
Assign variables to you unknowns.
c = $ cars
t = $ trucks
6c + 3t = 4800
8c + t = 4600
use substitution or elimination to solve the system of equations.
using elimination.. multiply second equation by -3 and add to the other to combine equations into one.
6c + 3t = 4800
-3(8c + t = 4600)
---------------------------
-18c + 0 = -9000
c = 9000/18
c = 500 $
use this in one of the equations to find the cost of a truck.
8(500) + t = 4600
4000 + t = 4600
t = 4600 - 4000
t = 600 $
question asks
2(500) + 3(600) =
1000 + 1800 = 2800 $
