Which shows the numbers in order from least to greatest?

gavmur [86]

So just convert to a common form
I will convert to decimal since 2 of them are already decimals

to conver 1 and 3/7 to decimal, just divide 3 by 7 using a calculator
1 3/7=1.43...

so 1.38, 1.43, 1.40
the greates is .43 then .40 then .38 so the order is

7+4(r+3)=9r-6<br> show work pls AND HELP ASAP

ivanzaharov [21]

$\: \: \: \: \: \:$

$= \: \: \: \: r = 5$

Step-by-step explanation:

$7 + 4(r + 3) = 9r - 6$

<em><u>distribute</u></em><em><u> </u></em>4 through the parentheses

$7 + 4r + 12 = 9r - 6$

add numbers

$19 + 4r = 9r - 6$

move the <em><u>variable</u></em><u> </u>to the left hand side and change its sign

$19 + 9r = - 6$

move the <em><u>constant </u></em>to the right hand side and change its sign

$4r - 9 = - 6 - 19$

collect<em><u> like</u></em><em><u> terms</u></em>

<em><u> $- 5r = - 6 - 19$ </u></em>

calculate the difference

$- 5r = - 25$

divide both sides of the equation by <em>-</em><em>5</em>

<em> $= \: \: \: \: r = 5$ </em>

On cyber Monday a 40$ hard drive was discounted by 30%. If the tax rate in your city is 7%, what is the total cost of the hard d

Georgia [21]

The total cost of hard drive is $29.96

Step-by-step explanation:

Given,

Original price = $40

Discount = 30%

Discount amount = 30% of $40 = $\frac{30}{100}*40$

Discount amount= $\frac{1200}{100}= \$12$

Price after discount = Original price - discount amount

Price after discount = 40-12 = $28

Tax rate = 7%

Tax amount = 7% of price after discount

$Tax\ amount=\frac{7}{100}*28\\Tax\ amount=\frac{196}{100}\\Tax\ amount=\$1.96$

Total cost of hard drive = Price after discount + Tax amount

Total cost of hard drive = 28+1.96 = $29.96

The total cost of hard drive is $29.96
