Answer:
75 hours
Step-by-step explanation:
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

6+ 4x = 8
or, 4x = 8-6
or, 4x = 2
x = 0.5
