To answer the question above, I let x be the number of calendars sold. You may use any other letter as this is just for representation. The total income generated in selling calendars is calculated by multiplying the number of calendars with the price. That is,
total income = 5x
If we let total income be y, our equation is further simplified into,
y = 5x

How can 3/7 divided by 2/4 be written in simplest form?

vova2212 [387]

Presenting your problem symbolically:

3
--
7

==== becomes
2
---
4

3
---
7

====

1
---
2

To divide by 1/2, multiply by 2/1:

3 2
-- * ---
7 1

Multiplying, we get 6/7.

The length of a rectangle is x feet more than its width. The area of the rectangle is 5x + 25. What is the width of the rectangl

AVprozaik [17]

Answer:

w = $l + \frac{25 - l^{2}}{l - 5}$

(Anyone can correct me if I'm wrong)

Step-by-step explanation:

Before we start the solving, we can make the following statements:

Area = l x w

Area = 5x + 25

therefore,

l x w = 5x + 25

Since the question states that the length is x more than the width, so we can make the following statement:

w = l + x

With this, we can substitute it to the first statement we made, l x w = 5x + 25,

l x (l + x) = 5x + 25

$l^{2}$ + lx = 5x + 25

lx - 5x = 25 - $l^{2}$

x(l - 5) = 25 - $l^{2}$

x = $\frac{25 - l^{2}}{l - 5}$

From this, we can find w by substituting it in the statement we made earlier, w = l + x,

w = $l + \frac{25 - l^{2}}{l - 5}$
