Step-by-step explanation:
Ralph (r): a + 5
Alphonse (a): a
Ralph + Alphonse = Total
(a + 5) + (a) = 73
2a + 5 = 73
2a = 68
a = 34
Ralph: a + 5 = 34 + 5 = 39
Answer: Ralph has 39 marbles, Alphonse has 34 marbles
The mapping rule for a 180 degree rotation is:
(x,y) (-x,-y)
1. Multiply the x-coordinate by -1.
2. Multiply the y-coordinate by -1.
3. SImplify
So the coordinate after a 180 degree rotation is: (5,-1)
