R divided by 14+5. I didn't know where the division sign was. Remember, the work only says to write
an expression, so you don't have to answer it unless it tells you to.
Let A be the amount of 100% acid.
100A+20*(6)=40*(A+6)
100A+120=40A+240
60A=120
A=2 gallons

Answer:
consistent, independent
Step-by-step explanation:
Systems of equations are most easily classified these ways if the equations are in the same form. If we solve the second equation for y, we have ...
y = x - 1
The x-coefficients of this and the first equation are different, so the system is <em>consistent</em> and <em>independent</em>.
__
A system is independent if the equations describe different lines.
A system is inconsistent if the equations describe parallel lines.
Here, the different lines are not parallel, so the system is independent and consistent.
