Let width = x, Therefore the length must equal 2x

Therefore insert these values on the sides of a rectangle.

Add: 2x + 2x + x + x = 18

Therefore 6x = 18

x = 3

olutions At the snack bar, hot dogs cost $4 each and bottled water costs $2 each. In the first business hour of the day, less th
ch4aika [34]

To solve the problem it is trial and error since we don’t know how many hotdogs and bottled water was sold. To trim down to problem, negative values and decimal values are not included because there is no negative amount and a decimal amount.

The equation is

4x + 2y > 12

At (0,6)

4(0) + 2(6) > 12

12 > 12 so it is wrong

At ( 2,1)

4(2) + 2(1) > 12

10 > 12 correct

At (1, 3)

4(1) + 2(3) > 12

10 > 12 correct

At (2,2)

4(2) + 2(2) > 12

12> 12 wrong

How do you simplify this equation?
faust18 [17]

<u>Answer:</u>

The answer is B --> \frac{x^{2} }{3x^{2} -1}

<u>How I got that:</u>

<u />

These are really easy, you're simply looking for numbers that you can factor down. Like here:

I took:

\frac{4x^{2} }{12x^{2} -4}

and saw that I could factor out 4 from the denominator:

\frac{4x^{2} }{4(3x^{2} -1)}

and then I canceled out the common factor (4 because its on both sides):

\frac{x^{2} }{3x^{2} -1}

And there ya go!

Austin is going to invest in an account paying an interest rate of 2.2% compounded daily. How much would Austin need to invest,
Korolek [52]

Answer:

  $23,700

Step-by-step explanation:

The compound interest formula can be helpful for this. Fill in the given values and solve for the unknown.

  FV = P(1 +r/n)^(nt)

where r is the annual interest rate, n is the number of times interest is compounded in a year, t is the number of years, P is the amount invested, and  FV is the future value of that investment.

  $27,000 = P(1 +0.022/365)^(365·6) = 1.1411037P

  P ≈ $23,700
