Answer: 78 and 80
Step-by-step explanation:
x + (x + 2) = 158
2x + 2 = 158
-2 -2
2x = 156; divide both sides by 2, and you get x = 78
If x = 78, then x + 2 = 80
Answer: 10.0 lb/wk
Step-by-step explanation:
1. Calculate the number of days
1 week = 7 days
2. Convert days to hours
24 h = 1 days
No. of hours= 7 days* 24h/1 day= 168h
3. Convert hours to ounces
1h = 0.952 oz
No. of ounces= 168h* 0.952 oz/ 1h=159.9 oz
4. Convert ounces to pounds
1 lb = 16 oz
No. of hours= 7 days* 24h/1 day= 168h
Therefore the biggest loser lost 10.0 lb per week.
