So it's actually 0.36363636... with the 36 repeating, right? 

<span>Here's a technique for converting repeating decimals to fractions: </span>

<span>N = 0.3636363636... </span>
<span>100N = 36.36363636... </span>

<span>This means 100N - N = (36.363636...) - (0.36363636...). This simplifies to 99N = 36, because the "0.36363636..." parts of both numbers on the right cancel each other out. </span>

<span>Solving this for N gives </span>
<span>N = 36/99, or 4/11 </span>

<span>If you take a calculator (or use long division) and divide 4 by 11, you'll see that it's 0.36363636...</span>

Marie spends $450.00 at a department store. She has two coupons: one for a 15% discount and one for $50 off any purchase above $
VMariaS [17]

Answer:

Her first coupon ti be used is $50 off a purchase above $300

Final purchase price= $340

Step-by-step explanation:

Marie has two coupons

one for a 15% discount and one for $50 off any purchase above $300.

The stores allow the two coupons to be combined and she spends a total of $450.

Her first coupon ti be used is $50 off a purchase above $300.

So Marie have $400 now

15% off $400= 400-(0.15*400)

15% off $400 = 400-60

15% off $400 =$ 340

Given:

The equation is:

3^x\times 9=3^{2n-1}

To find:

The value of n in terms of x.

Solution:

We have,

3^x\times 9=3^{2n-1}

It can be written as

3^x\times 3^2=3^{2n-1}

3^{x+2}=3^{2n-1}                [\because a^ma^n=a^{m+n}]

On comparing the exponents, we get

x+2=2n-1

Add 1 on both sides.

x+2+1=2n-1+1

x+3=2n

Divide both sides by 2.

\dfrac{x+3}{2}=n

Therefore, the value of n is terms of x is n=\dfrac{x+3}{2}.
