6 hours
Step-by-step explanation:
Im not sure but if correct brainliest i guess if not report my Question srry if not correct
The answer is A, 68 mirrors were broken in the process
16 times x=1200 or
16x=1200
divide both sides by 16
1200/16
so we simplify 1200/16 by factoring out the ones (4/8=1/2 times 4/4 since 4/4=1)
1200=3*2*2*2*2*5*5
16=2*2*2*2*1
so we notice that there are four 2's in both so those are the 'ones' so cross them off and get
3*5*5/1 or 75/1 or 75 hours
The answer should be the second choice, “B”
A would be subtracting the exponents, while C & D are adding exponents
