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 $
5/8 i think if i’m wrong i’m soo sorry
we know that
the fourth point is plotted 5 units to the right of (-4,4)
so
the coordinate x of the fourth point is equal to
-4+5=1
the y-coordinate of the fourth point is the same y coordinate of (-4,4)
therefore
the coordinates of the fourth point is (1,4)
9 can only go into 32, three times so you will have 5 leftover so that can be written as 3 5/9. You can also check this by taking the denominator of 9 and multiplying it by the whole number 3..this is 27 and then add the numerator 5 to it.
So 9*3+5= 32 and then add a denominator.. 32/9.
