Let Jimmy have x silver dollars
then tom have 7+x silver dollars .
from the given condition :
x + x+7 = 71
2x = 71-7
2x=64
x=32
then 32+7 = 39
so tom will have 39 silver dollars.
Let's say that the coordinates of the squirrel are: (x, y)
Since the coordinates of the acorn is halfway, between the tree and the squirrel, that means the acorn is the midpoint.
To work out the midpoint you do:
(sum of x-coordinates) divided by 2, (sum of y coordinates) divided by 2.
We can use this to form an equation .
So the sum of the x coordinates of the tree and the squirrel = -1 :
x-coordinates of the squirrel:
<em>(now solve for x)</em>
y-coordinates:
<em>(now solve for y)</em>
So the coordinates of the squirrel are: (1, 2)

Answer:
(1, 2)
Answer: Part A:
We observe that we have the following system of equations:
y = 4x
y = 2x-2
The solution to the system of equations is an ordered pair (x, y), that is, a point in common that both functions have.
Part B:
x y = 4x y = 2x-2
-3 -12 -8
-2 -8 -6
-1 -4 -4
0 0 -2
1 4 0
2 8 2
3 12 4
The solution is the ordered pair:
(x, y) = (-1, -4)
Part C:
