Answer:
Ryan's revenue last month if he sold 16 new books and 25 old books
is $337.50.
Step-by-step explanation:
The number of old books sold by Ryan = 25
The cost of each old book = $5.50
⇒ Total amount earned by selling 25 old books = 25 x $5.50
= $137.5
The number of new books sold by Ryan = 16
The cost of each new book = $12.50
⇒ Total amount earned by selling 16 new books = 16 x $12.50
= $200
Hence Total amount earned by Ryan
= Amount earned by selling old books + Amount by selling new books
= $137.5 + $200
= $337.50
or, Total amount earned by Ryan = $337.50
Hence Ryan's revenue last month if he sold 16 new books and 25 old books is $337.50.
If f(x) = 3x - 12 and x = 9
then substitute 9 in place of x
f(9) = 3(9) - 12
f(9) = 27 - 12
f(9) = 15

<h2>
<em>step</em><em> </em><em>1</em><em> </em><em>:</em><em>study</em><em> </em><em>the</em><em> </em><em>problem</em><em> </em></h2>
<em>write</em><em> </em><em>down</em><em> </em><em>your</em><em> </em><em>fact</em><em> </em><em>or</em><em> </em><em>what</em><em> </em><em>you</em><em> </em><em>know</em><em> </em><em>about</em><em> </em><em>the</em><em> </em><em>problem</em><em>. </em><em>also</em><em> </em><em>crossout</em><em> </em><em>unnecessary</em><em> </em><em>parts</em><em> </em><em>of</em><em> </em><em>the problem</em><em> </em><em>and</em><em> </em><em>highlight</em><em> </em><em>important</em><em> </em><em>information</em><em>.</em>
example: X = hours
<h2> </h2><h2>Step 2: organize your facts</h2>
organize your facts means put in order ,write what it means etc.
example: the problem say rebbeca has 3 3 times as much candy than Sara. what does the problem mean ?
<h2>Step 3 : line up your strategy. </h2><h3> what are your plans for solving this problem ? what operation will u do ? how much step is in this problem ? does this make sense ? in line up your strategy u have to think about why I'm doing this? how I will do this etc.</h3>
<h2>Step 4 : validate </h2>

The equation for finding the <em>AREA </em>of a<em> TRIANGLE </em>is simply: half times base times height, or, 1/2xbxh.
The base here is 6
The height here is also 6
Substitute these values into the formula!
1/2 * (6) * 6)
Multiply!
1/2 * 36.... (6 * 6 = 36)
1/2 * 36 = 18
So, the triangle is 18 sq. units!
