3b + r = 20
20/4=5
5x3=15 blue pens
5x1= 5 red pens
77 ball point pens. Let x be the number of pens in a box. Then: number_of_pens = 6x + 5 = 5x + 17 so solving: 6x + 5 = 5x + 17 ⇒ x = 12 ⇒ number_of_pens = 6 x 12 + 5 = 77
Depends on the size of the box. You can use the formula length times width times height, though.
Multiplying the length times the width, times the heighth- will give you the volume of the cubic measurement of a box.
The dimensions of a Kleenex box are length, width and height. The volume of the box is equivalent to length times width times height.
First of all, there's probably no other way to find it except with math.-- Add up:(length of the box times width of the box) plus(length of the box times height of the box) plus(width of the box times height of the box).-- Double the result.-- You have the total area of the cardboard used to make the box, including its top.
12 x 3 = 36 12 x 8 = 96 96 - 36 = 60 there are 60 blue pens in the box.
There are typically 12 pens in a standard box.
The answer is 16. The reason for this is if half the box is 24, then the whole box had 48 pens. 48 divided by 3 (because its a third) it leaves you with 16.
5 were purple
In 4 boxes there are a total of 48 pens. Divide 48 by 4 and this will give you how many pens are in 1 box. 48/4 = 12. To find how many pens are in 9 boxes multiply 12 by 9. 12x9 = 108. There are 108 pens in 12 boxes
The sentence "There are five pens in the box" is grammatically correct.
