Answer:
D 18
Step-by-step explanation:
Let r = red pens
b =5r
g = 3r
The total number of pens
r+b+g
Substitute
r + 5r+ 3r
Combine like terms
9r
The number of pens must be a multiple of 9
18 is a multiple of 9

Answer:
x = 8.33 meters
Step-by-step explanation:
what is x in meters?
The line segment addition postulates states that given two endpoints A and C with a point B placed between point A and point C, then the points A, B and C meets the equation:
AB + BC = AC
Since point P is between point A and point C. Hence the following equation holds:
AC = AP + PC
Substituting values:
25 = 3x - 8 + 8
3x = 25
x = 25/3
x = 8.33 meters
AP = 3x - 8 = 3(8.33) - 8 = 17 meters
The first thing you should do is to<span> divide the total cost by the unit cost you have got: </span><span>(2y^2 + 6) / (y^2 - 1) </span>
Then just use simple math by plugging in the value y=3
(2*3²+6): (3²-1)= 24:8 = 3 which is the nubmer of the bought notebooks.
<span>In total he spent $24 on notebooks that cost $8.</span>
1 4/5-5/6
9/5-5/6
54/30-25/30=
29/30 more miles
