"Dram" is a unit of volume, whereas "gram" is a unit of mass.
They can't be directly converted. If they both refer to a sample
of some substance, then the conversion depends on the density
of the substance. All we can say for sure by way of an answer is:
To change 'drams' to 'grams', replace the 'd' with 'g'.
10. The constant of proportionality would be 0.07 because in the equation y=kx 0.07 is substituted for k which stands for the constant of proportionality.
11. The equation is t=45d because for every hour you travel 45 miles (or 90/2, 135/3, etc.)

Answer:
all are showing that y is a function of x
The first step for solving this expression is to know that since both of the expression are equal to y,, we must set them each to each other to form an equation in x. This will look like the following:
-3x + 7 = -3x - 6
Now cancel equal terms on both sides of the equation.
7 = -6
This tells us that the statement is false for any value of x and y,, so our answer is (x,y) ∈ ∅,, or no solution (option D).
