Answer:

Step-by-step explanation:

A car is rented for $40 per day plus $0.25 per mile driven. The total is $45.50-  40 + 0.25x + 45.50

Karen buys four t-shirts for $45.50. The three red t-shirts each cost 4 times the price of one blue t-shirt.- x + 3(4x) = 45.50

Finn buys a toy boat for $45.50 including tax He was charged 7% sales tax on the original price.- X+0.07% = 45.50

Nick buys a sweater and a jacket for $45.50. The jacket costs 4 times as much as the sweater- 1 X + 4x = 45.50

If the interest rate on a savings account is 0.02%, approximately how much money do you need to keep in this account for 1 year
astraxan [27]
At first glance, this problem might be overwhelming so try approaching it slowly by doing these steps:

Step 1: Start by understanding what the problem is really asking.
You might notice that the problem is just a percentage problem, with a twist! If you still don't see it, the problem is just asking what the base should be given a percentage and the amount.

Step 2: Recall the concepts relevant to the question.
We can identify a single formula that will be important in getting the answer:
base*percent=amount

Step 3: Apply the concept to the context of the problem.
You'll see that we already have the percent from the interest rate which is 0.02% and the amount from the below-minimum-balance fee which is $9.99.

There goes the little twist: you have to manipulate the equation to get the base. Dividing both sides of the equation by the percent we'll have:
base= \frac{amount}{percent}

Step 4: Evaluate to get the answer to the problem.
We simply substitute the given numbers and evaluate.
base= \frac{percent}{amount}= \frac{9.99}{0.0002} =49,950

Answer: You need $49,950 in the account to cover the Below-Minimum-Balance Fee from your interest.

Which expression is equivalent to the following complex fraction?
ivanzaharov [21]
<h2>Answer:</h2>

The expression which  is equivalent to the following complex fraction is:

                   \dfrac{-2y+5x}{3x-2y}

<h2>Step-by-step explanation:</h2>

We are given a expression in terms of two variables x and y as follows:

\dfrac{\dfrac{-2}{x}+\dfrac{5}{y}}{\dfrac{3}{y}-\dfrac{2}{x}}

Now, on taking least common multiple in the numerator as well as in the denominator we have:

\dfrac{\dfrac{-2y+5x}{xy}}{\dfrac{3x-2y}{xy}}

which on further simplifying is:

\dfrac{-2y+5x}{3x-2y}

What polynomial can be factored to give (a + 4) ( a - 4) ?​
iragen [17]

Answer:

(a+4)(a-4)=a²-4²   ITS LIKE THIS BECAUSE ITS AN IDENTITY,

               ⇒a²-16

Even when we solve it by the regular method of solving polynomials we get a²-16 as answer as there and thats the proof for the identity.

(a+b)(a-b)=a(a-4)+4(a-4)

⇒a²-4a+4a-16

⇒a²-16[NOTE:-4a+4a=0]

Thus we can see that a²-16 is the answer we get when we try to solve it by regular polynomial solution tooo.

And a²-16 is the polynomial from which we get (a+4)(a-4)

One-third of a number is 12<br> Work out one-half of the number
marshall27 [118]

If 1/3 = 12, then multiply 12 by 3 to get the number, which is 36

then split 36 in half, and you get 18.

hope this helps!
