1/4x^2 = -1/2x + 2.....multiply everything by 4
x^2 = -2x + 8
x^2 + 2x - 8 = 0
(x + 4)(x - 2) = 0

x + 4 = 0
x = -4

x - 2 = 0
x = 2

solutions are : x = -4 or x = 2

I’m Atlanta, the tax on a property assessed at $930,000 is $19,530. If tax rates are proportional in this city, how much would t
igomit [66]

Answer:

The tax on property assessed at $660,000 is  <u>$13860 </u>.

Step-by-step explanation:

Given:

In Atlanta the tax on a property assessed at $930,000 is $19,530.

The tax rates are proportional to this city.

Now, to find the tax on a property assessed at $660,000.

So, <em>we need to get the tax rate of Atlanta first.</em>

Tax Rate = Tax / Property assessed × 100.

Tax\ rate=\frac{19530}{930000} \times 100

Tax\ rate=0.021 \times 100

Tax\ rate=2.1\%

<em>According to question the</em><u><em> tax rates are proportional.</em></u>

<em>So, </em><u><em>for getting the tax in this city we use the same rate of Atlanta</em></u><em>:</em>

Tax = tax rate of property assessed.

Tax = 2.1\% of\ \$660,000

Tax = \frac{2.1}{100}\times 660000.

Tax = 0.021\times 660000

Tax=\$13860

Therefore, the tax on property assessed at $660,000 is $13860.

A man drove x miles per hour for 3 hours and (2x-60) miles per hour for the next 4.75 hours. A)Express the total distance travel
erik [133]

Answer:

12.5x-285.

Step-by-step explanation:

We are told that a man drove x miles per hour for 3 hours, so he traveled 3x miles in three hours.

We are also told that he drove (2x-60) miles per hour for the next 4.75 hours. So The distance traveled by in next 4.75 hours will be:

4.75\cdot (2x-60)=9.5x-285  

To find the total distance traveled by man we will add distances traveled by him in first 3 hours and next 4.75 hours.

\text{The total distance traveled}=3x+9.5x-285

Upon combining like terms we will get,

\text{The total distance traveled}=(3+9.5)x-285

\text{The total distance traveled}=12.5x-285

Therefore, the total distance traveled in terms of x will be 12.5x-285.

Step-by-step explanation:

7/15 + 3/5

I'd multiply 3/5 by 3 so that both of the denominators (bottom number) are the same.

Now all we have to do is add the Numerators tog

7/15 + 9/15ether (the top number)

7/15 +9/15 = 16/15 or 1 1/15

Compare fraction 2over 3 and 7 over 8 which is greater
Paul [167]
If you use a calculator to find the exact decimal of these fractions, you can easily find this out.

2/3 as a decimal equals:  0.6666 (repeating sixes)

7/8 as a decimal equals:  0.875

0.875 > 0.666

7/8 > 2/3

7 over 8 is greater!  Hope this helps! :)
