Hakim had 19 bottles of water on Monday.
To find out how many bottles of water Hakim had on Monday, we need to work backwards from the information given. On Wednesday, he had 7 bottles of water which was half of his collection. So, if we double 7, we can find out how many bottles he had in total, which is 14. On Tuesday, he purchased 5 more bottles, so the total number of bottles he had on Tuesday was 14 + 5 = 19. Therefore, Hakim had 19 bottles of water on Monday.

Answer:
4 sqrt(5)
Step-by-step explanation:
7 sqrt(5) - 3 sqrt(5)
These are like terms so we can subtract
4 sqrt(5)
To simplify a radical expression 7√5 - 3√5, subtract the coefficients and keep the radicand the same. The simplified expression is 4√5.
To simplify the given expression, we need to combine the terms involving square roots. We can notice that the terms have the same radicand, which is 5. So, we can combine them by subtracting the coefficients. The simplified expression is:
7√5 - 3√5 = (7 - 3)√5 = 4√5
