Answer:
1241
Step-by-step explanation:
∴
L.C.M. of 28, 36 and 45 = 2 × 2 × 3 × 3 × 5 × 7 = 1260
∴
the required number is 1260 - 19 = 1241
Hence, if we add 19 to 1241 we will get 1260 which is exactly divisible by 28, 36 and 45.

Answer: 36 cars and 9 motorcycles
Step-by-step explanation:
- It's given that he has x motorcycles to 4x cars
- After he bought the cars and sold the motorcycles, he had 4x+4 cars to x-4 motorcycles
- Since after this selling/buying, he has 8 times more cars than motorcycles, you can write the equation 4x+4=8(x-4)
- Once you solve you get 36 cars and 9 motorcycles
The solution for the #23 equation is either x=9 or x= -3
