The constant of proportionality in this situation is 32 and it represent the miles.
m = 32 x g can be interpret as
m(average number of miles) = 32(miles) X g(gallon)
The correct answer for the question that is being presented above is this one: "C) 3 tons from source A, 0 tons from source B." The tons of ore from each source should be processed each day to maximize the amount of steel produced is that <span>C) 3 tons from source A, 0 tons from source B </span>
Answer:
c=0
Step-by-step explanation:
5(2c-3)=3(3c-5)
Expand parentheses:
10c-15=9c-15
Add 15 to both sides:
10c=9c
The only way that this could be possible is if c was 0. Hope this helps!

Step-by-step explanation:
Hi there!
We're given this system of equations:
x+y=3
4y=-4x-4
and we need to solve it (find the point where the lines intersect, as these are linear equations)
let's solve this system by substitution, where we will set one variable equal to an expression containing the other variable, substitute that expression to solve for the variable the expression contains, and then use the value of the solved variable to find the value of the first variable
we'll use the second equation (4y=-4x-4), as there is already only one variable on one side of the equation. Every number is multiplied by 4, so we'll divide both sides by 4
y=-x-1
now we have y set as an expression containing x
substitute -x-1 as y in x+y=3 to solve for x
x+-x-1=3
combine like terms
-1=3
This statement is untrue, meaning that the lines x+y=3 and 4y=-4x-4 won't intersect.
Therefore the answer is no solutions
Hope this helps! :)
The graph below shows the two equations graphed; they are parallel, which means they will never intersect. If they don't intersect, there's no common solution
