Answer:
$27 per book
Step-by-step explanation:
258 - 9(books) = 15
258-15 = 243
243 / 9=27

Answer: 0</h3>
To get that answer, apply the slope formula
m = (y2 - y1)/(x2 - x1)
m = (-8 - (-8))/(9 - (-2))
m = (-8 + 8)/(9 + 2)
m = 0/11
m = 0
Any line with slope 0 is completely horizontal.
As a quick rule of thumb: if the y coordinates of the two points are the same, then the slope is 0 on this horizontal line.
<em>Step 1: Subtract x from both sides. </em>
1/3x +4− x =x −2− x
= -2/3 x +4 = -2
<em>Step 2: Subtract 4 from both sides</em>.
-2/3x + 4− 4 =−2− 4
-2/3x = -6
<em>Step 3: Multiply both sides by 3/(-2).</em>
( 3/-2 ) * (-2/3x ) = (3/-2) * (-6)
= 9
So , X=9
Answer: 7.5v+30=90, v=8
Step-by-step explanation:
He earns 7.5 points per visit, make 7.5 your coefficient. V is your variable. Therefore your equation is 7.5v+30=90, and after solving you get v=8
