Answer:

\huge \boxed { \boxed{x =  \{6 , - 6 \}}}

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • absolute value
  • equation
  • PEMDAS
<h3>tips and formulas:</h3>
  • |a|=±a
<h3>let's solve:</h3>
  1. \sf divide \: bothe \: sides \: by \: 5 :  \\  \frac{ 5|2x| }{5}  =  \frac{60}{5}  \\  |2x|  = 12
  2. \sf seperate \: the \: equation \:in \: 2 \:parts :  \\  \begin{cases}2x = 12 \\   \: 2x =  - 12\end{cases}
  3. \sf \: di vide \: both \: sides \: by \: 2 : \\  \begin{cases}  \frac{2x}{2} =  \frac{12}{2}  \\   \:  \frac{2x}{2}  =   \frac{ - 12}{2} \end{cases} \\  \therefore  x =   \{6 , - 6 \}

Can someone please teach me how to to this<br> Item: $30 Discount: 15%
seraphim [82]

Answer:

$25.5

Step-by-step explanation:

Sure, so the total of the

Item:

30 Dollars ($)

and the discount price is

15 percent (%)

So 30 times 0.15 because 30 is the price in total and 0.15 is the percentage but in a decimal form.

30 times 0.15 equals 4.5

4.5 is the amount that 15 % equals.

30 minus (-) 4.5 because once again the total is 30 and since we have a discount price then we minus (-) the discount price by the total and you get

A total with the discount price as 25.5 Dollars or $25.5

Hope this helps ;)

Let ​f(x)equals=33xminus−​1, ​h(x)equals=startfraction 7 over x plus 5 endfraction 7 x+5 . find ​(hcircle◦​f)(66​).
Ronch [10]
\bf \begin{cases}&#10;f(x)=3x-1\\&#10;h(x)=\cfrac{7}{x+5}\\\\&#10;(h\circ f)(x)=h(~~f(x)~~)&#10;\end{cases}&#10;\\\\\\&#10;f(66)=3(66)-1\implies \boxed{f(66)=197}&#10;\\\\\\&#10;\stackrel{h(~~f(x)~~)}{h(~~f(66)~~)}\implies \stackrel{h(~~f(66)~~)}{h\left(~~\boxed{197}~~ \right)}=\cfrac{7}{\boxed{197}+5}\implies h\left(~~\boxed{197}~~ \right)=\cfrac{7}{202}

A gardener wishes to plant plants in such a way that each row contains as many plants as the number of rows. He has 2624 plants.
vagabundo [1.1K]

Answer:

80

Step-by-step explanation:

we search for a square number so that rows*plantsInARow gives us the number

The number should be around 50², guessed

50² = 2500 (to low)

51² = 2601 (still to low)

52² = 2704 (bingo)

now to get from 2624 to 2704 plants he needs 80 more. That is the least number.

He could also go to plant 60² plants an than need slot more.

(would really appreciate the brainliest)

Circumference and Area of Circles
yanalaym [24]

Step-by-step explanation:

Area of a circle = #r^2

1256 = 3.14 × r^2

r^2 = 1256/3.14

r^2 = 400

Square root of r = 20

Diameter = 2 × r = 2 × 20 = 40 inches
