Answer:
18km
Step-by-step explanation:
speed=distance\time taken that's the formula I've used.I hope you'll understand it.
Step-by-step explanation:
You have 120 bottles of Cola and 120 bottles of Sprite.
You can exchange 3 empty Cola bottles for a new bottle of Sprite.
You can exchange 4 empty Sprite bottles for a new bottle of Cola.
You can borrow empty bottles, but must return them in the end.
What is the maximal number of bottles of drink that you can drink? Prove the optimality of your result.
As this is a puzzle, please give short and clever answers rather than tedious bruteforce calculations.
Given:
Price of new computer at local store = $1,449
This is 18% less than what it costs at the Brownstone Mall.
To find:
The cost of new computer at the Brownstone Mall.
Solution:
Let x be the cost of new computer at the Brownstone Mall.
According to the question,
Divide both sides by 0.82.
Therefore, the cost of new computer at the Brownstone Mall is $1767.07.
The answer is A, positive. As you can see all the dots are all moving upwards.
Alright. If we're multiply 3x by 3x, we can think of this as :
3 × x × 3 × x (since 3x is really just 3 × x)
We see that since it's all being multiplied together, it doesn't matter what order we do. 3 times 3 is 9, so we now have
9 × x × x
When multiplying the same type of variables, we add their exponents. if an exponent isn't shown, it's understood that there's an invisible 1 there. So we really have x^1+1 once we multiply x×x. So really, x × x is x^2. so, I now have:
9 × x^2 or 9x^2
I see that this isn't an available solution. Please recheck your answers, or what the original problem was. I can assure you that with the info provided, 9x^2 is undoubtedly the answer. Perhaps you meant 3x + 3x?
For the second problem, we just have to see how many times we need to add 5 to itself until we get 20. How many times we have to add is how many months he has to save.
5 + 5 + 5 + 5 = 20
So, 4 times, means he has to save for 4 months.
Hope this helps, and please let me know what happened with question 1!
