Answer:
slope= 5/4
Step-by-step explanation:
The slope equation is (change in y)/(change in x), so you can take two points and use the equation.
The answer could be 48/5 or 9 and 3/5 or 9.6 These all mean the same exact thing. You get the answer by multiplying 12/1 and 4/5 to get 48/5.
We do as follows:
let x = amount of 45% solution
y = amount of 30% solution
overall balance => x + y = 450
acid balance => .45x + .30y = .40(450)
Solving simultaneously, we will have:
x = 300 mL
y = 150 mL
This is assuming that partial molar properties does not affect the volume greatly. Hope this answers the question. Have a nice day.
quotient is divide 7 ÷ -3/6
now flip the -3/6
7/1 x -6/3 = -42 / 3 or -14
Step-by-step explanation:
36-5x=5-6x+24
-5x+6x=24+5-36
x=29-36
x=-7
