Answer:

Step-by-step explanation:

Total money = $20

amount for mailing package = $ 3.67

Price for one stamp = $ 0.37

Let number of stamps be x,

Price for x stamps = $.037x

Price for x stamps + amount for package should not exceed $20

0.37x+3.67 ≤ 20

Solving for inequality,

x≤ 44.1

Since x should be whole number,

x ≤ 44

Answer:

<h2>x = 4</h2>

Step-by-step explanation:

x + 2 =  \frac{x}{4}  + 5

Multiply through by 4 to eliminate the fraction

That's

4x + 8 =  \frac{x}{4}  \times 5 + 5 \times 4 \\ 4x + 8 = x + 20

<u>Subtract x from each side</u>

That's

4x  - x + 8 = x - x + 20 \\ 3x  + 8 = 20

<u>Subtract 8 from each side</u>

3x + 8 - 8 = 20 - 8 \\ 3x = 12

<u>Divide both sides by 3</u>

\frac{3x}{3}  =  \frac{12}{3}

We have the final answer as

<h3>x = 4</h3>

Hope this helps you
