Let b be the initial amount of books. Steve sells half of his books, so the number of Steve's books become
Then, he buys 6 more, so the number increases by 6:
This number is now 14, so you have
Subtract 6 from both sides:
Multiply both sides by 2:
9514 1404 393
Answer:
9 7/12
Step-by-step explanation:
12 is a suitable common denominator.
(7 3/4) + (1 5/6) = (7 9/12) + (1 10/12) = (7+1) +(9/12 +10/12)
= 8 + 19/12 = 9 + 7/12 . . . . . . change 19/12 to 1 7/12
= 9 7/12
_____
My calculator works with mixed numbers very nicely, as many graphing calculators do.
£36.48.
1. Multiply 38 by 0.04 (4% in decimal) and you’ll get 1.52
2. Subtract 1.52 from 38 to get 36.48
Answer:
see below
Step-by-step explanation:
1 million
1,000,000 seconds * 1 hour/ 3600 seconds * 1 day/ 24 hours * 1 year / 365 days
.031709792 years
Rounding to 3 decimal places
.032 years
50 years * 365 days/ 1 year * 24 hours/ 1 day * 3600 second / 1 hour
1577000000 seconds
46 inches * 1 ft/ 12 inches * 1 mile/5280 ft
0.000726 miles
2/3 + 3/4 = 8/12 + 9/12 = 17/12 = 1 5/12
1 + 5/12 = 12/12 + 5/12 = 17/12 = 1 5/12
2/3 + 3/4 = 1 + 5/12
