Move variables to the left by adding their opposites to both sides. Eliminate the opposites.
Move constants to the right by adding their opposites to both sides. Eliminate the opposites.
Collect the like terms by subtracting their coefficients and numbers.
Calculate the sum or difference. Extract the negative sign from the expression. Add the numbers.
Divide both sides of the equation by 5 and calculate the quotient.
1. ratio = 2 c of dressing / 4 lb of vegetables
Use two variables: d for the number of c of dressing and v for the number of pounds of vegetables.
Then d / v = 2/4 = 1/2 => d = v/2
Now you can make a table
v d
2 1
4 2
6 3
8 2
And you can draw a line for the points (2,1); (4,2); (6,3), (8,4) ... the slope of the graph is the ratio = 1/2
b) I already did it above as part ot the explanation: d/v = 1/2
The answer is C an example is 20% of $20 is 4, so you would lose the zero and double the 2 to get 4

Answer:
D) No Solutions
Step-by-step explanation:
The lines have the same slope (-4), but different y-intercepts (3, 0), so they are parallel lines. There can be no values of x and y that satisfy both equations.
There are no solutions.
