1345-11:15 = 2:30
Step-by-step explanation:
Let x = Number of pounds of Horse Food
Let y = Number of pounds of Medical Supplies
so
0.3x+0.4y=8000----1
x+y=20000-----------2
multiply eqn 2 by 0.3 to eliminate x we have
0.3x+0.4y=8000
0.3x+0.3y=6000
-0+0.1y=2000
0.1y=2000
y=2000/0.1
y= 20000
put y=2000 in eqn 2
x+20000=20000
x=20000-20000
x=0
its quite unfortunate that for her to maximize the opportunity and the money she has to carry 20,000 pounds of only Medical Supplies

Answer:
A
Step-by-step explanation:
Convert the symbols in the diagram to an algebraic equation
3x + 6 = 5x + 2 ( subtract 3x from both sides )
6 = 2x + 2 ( subtract 2 from both sides )
4 = 2x ( divide both sides by 2 )
2 = x ⇒ x = 2 → A
