Answer:
C) 84
Step-by-step explanation:
5.7 pints would be water
3/10 of 19 pints are water
19*(3/10) = 5.7
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 $
Answer:
60°
Step-by-step explanation:
since all sides of a triangle are equal .The given triangle is an equilateral triangle. And each angles of an equilateral triangles is 60 degree.So angle A is also 60 degree.
