Jill and Ben have the same pens Jill has 3 full boxes of pen and 2 loose pens Ben has 2 full boxes of pen and 14 loose pens how

defon

Let x be the number of pens in a box.

Jill : three full boxes of pen and 2 loose pens. 3x + 2
Ben: two full boxes of pen and 14 loose pens. 2x + 14

Jill and Ben have the same pens.
Jill = Ben
3x+2 = 2x + 14
3x - 2x = 14 - 2
1x = 12
x = 12

To check:
Jill    =   Ben
3x + 2    =   2(x) + 14
3(12) + 2 =   2(12) + 14
36 + 2 =   24 + 14
38 = 38

There are 12 pens or a dozen of pens in a full box.

The Pythagorean Theorem- Find the Missing Length:

drek231 [11]

The miles he drove North on Avenue B is 24 miles.

<h3>What is Pythagoras theorem? </h3>

According to the Pythagoras theorem, the square of the hypotenuse is the sum of the square of the opposite sides.

The Pythagoras theorem: a² + b² = c²

Where:

a = length
b = base = 7 miles
c = hypotenuse = 25 miles

<h3>How many miles did he drive north of Avenue B? </h3>

25² - 7²

625 - 49 = 576

√576 = 24 miles
