19 4-cent stamps and 3 28-cent stamps should be used.
Given that Greg needs at least $ 1.60 in stamps to mail a package, and he has 28cent stamps and 4cent stamps, and he can use no more than twenty 4cent stamps as he only has one book left, to determine how many stamps to use should be made the following calculation, through a linear function:
- (0.04 x 20) + 0.28X = 1.60
- 0.80 + 0.28X = 1.60
- 0.28X = 1.60 - 0.80
- 0.28X = 0.80
- X = 0.8 / 0.28
- X = 2.85
- (3 x 0.28) + 0.04X = 1.60
- 0.84 + 0.04X = 1.60
- 0.04X = 1.60 - 0.84
- 0.04X = 0.76
- X = 0.76 / 0.04
- X = 19
Therefore, 19 4-cent stamps and 3 28-cent stamps should be used.

Get a common denominator first.
89/120 becomes 1157/1560
90/130 becomes 1080/1560
Subtract the two and you get 77/1560
Answer:
If total maths hw time = 90 minutes, time spent on word problems = 1/2 hour
Step-by-step explanation:
Let the time available for maths homework be = 90 minutes. It is equal to 1.5 hour (as 1 hour = 60 minutes, 0.5 hour = 30 minutes).
1/3rd of maths homework time, ie 1/3rd of 90 minutes = 30 minutes, is used in doing word problems. These 30 minutes correspond to half (1/2 or 0.5) of an hour, as 1 hour = 30 minutes.
The correct answer is the larger one is 30 and the smaller one is 12 because 42-18 gives you 24 so you do 24/2 you get 12 so you add 18 to one of the 12s and you get the answer as 12 and 30
