Answer: x=6 y=6
Step-by-step explanation:

Since the right parts of the equation are equal, therefore the left parts of the equation are also equal:

Divide both parts of the equation by 2:

Answer:
19 nickel = .95
5 dimes = .50
Step-by-step explanation:
.95 + .50 = 1.45
Answer: see last picture
Step-by-step explanation:
We see that the y-intercept is 10 and the slope is -3
so when x = 0, y = 10
Graph this first point (picture 1)
Since the slope is -3, every time you go one unit to the left, you go down 3 units, so graph this second point (picture 2)
Continue this until you have no more room on the graph (picture 3)
now draw a line through the dots (picture 4)
The consecutive integers are -1
If 0.3 = 1 then 0.9 = 3 because 0.3+0.3+0.3=the 3.
