Question

If 5 times a number is increased by 4, the result is at least 19. Find the least
possible number that satisfies these conditions.

Answer 1

Answer:

3

5 times a number would be 5x, then increase that by 4 is 5x+4. The problem then says 5x + 4 ≥ 19. If we solve for x then we get x ≥ 3 so x has to be greater than or equal to 3, so the smallest number it could be is 3.
