Answer:
Use multitape Turing machine to simulate doubly infinite one
Explanation:
It is obvious that Turing machine with doubly infinite tape can simulate ordinary TM. For the other direction, note that 2-tape Turing machine is essentially itself a Turing machine with doubly (double) infinite tape. When it reaches the left-hand side end of first tape, it switches to the second one, and vice versa.
Answer: if the blue rectangles are x, then x = 1/2
1/2 + 1/2 = 1
the green shapes each = 1
so you have 1 + 1 + 1 = 3 which is true so
x = 1/2
Step-by-step explanation:
Not a 100% positive this is the answer but i think it is 2.5
got this by dividing 30 by 12 and got 2.5
Your answer was correct . Maybe you have an extra space in your answer ? I worked out the problem twice and got -49/8, -163/8
