On Monday,hakim stocked up on bottled water for the trip. On Tuesday, he purchased five more bottles to add to his collection. On Wednesday, half of his entire collection remained and he only had 7 left. How many did he have on Monday?

Answers

Answer 1
Answer: 9 bottles

Because he drank half so at the climax he had 14, then he had bought 5 bottles on Tuesday so on Monday he had 5 less
Answer 2
Answer:

Final answer:

Hakim had 19 bottles of water on Monday.

Explanation:

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.

What is the sum of 2/5 and 2/4?

Answers

Make sure they are under the same denominator:

2/5 x 4 = 8/20
2/4 x 5 = 10/20

= 18/20
= 9/10 (simplified)

Can someone explain how to find the answer to this equation in steps?

2^2x = 8^x-1

Answers

remember
(x^(m))^(n)=x^(mn)
and
if a^x=a^y where a=a, then x=y so
make bases the same



2^(2x)=8^(x-1)
8=2^3
8^(x-1)=(2^3)^(x-1)=2^(3(x-1))
2^(2x)=2^(3(x-1))
threfor
2x=3(x-1)
2x=3x-3
0=x-3
3=x

Final answer:

To simplify a radical expression 7√5 - 3√5, subtract the coefficients and keep the radicand the same. The simplified expression is 4√5.

Explanation:

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
