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:
3
Step-by-step explanation:
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. You can even try any number smaller than 3 and see it doesn't work. even something like 2.9
Answer:
x ≥ 3
Step-by-step explanation:
Let the number = x
5 × the number = 5x
Increased by 4 means 5x +4
Is at least 19 means ≥ 19
5x + 4 ≥ 19
5x ≥ 15 Subtracted 4 from each side
x ≥ 3 Divided each side by 5
The smallest possible number that satisfies the conditions is x = 3.

Answer:
97.35
Step-by-step explanation:
355.5 - 235.5 -22.65
I am subtracting 235.5 and 22.65 from 355.5 because I am spending that much money on the things.
=> 355.5 - 235.5 - 22.65
=> 120 - 22.65
