Step-by-step explanation:

Thus, the HCF is (x+y).
I think this is.. ↓
grows 4% at every year
after 7 years ↓↓
4 × 7 = 28
A town has a population of 5000

Answer:
Step-by-step explanation:
1 cheeseburger and 20 fries
5384=5000+384
4 * 5384 = 4(5000+384) = 4 * 5000 + 4 * 384
4 * 5000 = 20000
20000 + 4 * 384
So to find 5384 * 4, you add 20000 to 4*384. Less calculations
