Answer:
1.12 x 
Step-by-step explanation:
To solve, move the decimal back until you are past the 0s. It has to be moved back 4 times to get to the first 1.
1.12
Now, since you went back 4, the exponent of 10 is -4.
x-5= 0
move -5 to the other side
sign changes from -5 to +5
x-5+5= 0+5
x= 5
x-6= 0
x-6+6= 0+6
x= 6
Answer: B. 5 and 6
