The number of 3¢ stamps that are in the collection is: 22.

<h3>What is an expression?</h3>

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

In this exercise, you're required to determine the number of 3 cents (3¢) . Therefore, we would translate the word problem into an algebraic expression and then evaluate it as follows:

<u>Note:</u> 100 cents (¢) is equal to 1 dollar ($).

A collection of stamps consists of 3¢ stamps, 5¢ stamps and 7¢ stamps; 3¢ + 5¢ + 7¢ = 194

6 more 3¢ stamps than 5¢ stamps; 3¢ = 5¢ + 6  ⇒ 5¢ = 3¢ - 6

Two more 7¢ stamps than 3¢ stamps; 7¢ = 3¢ + 2

Combining the above equations, we have:

3¢ + 3¢ - 6 + 3¢ + 2 = 194

9¢ = 198

¢ = 198/9

¢ = 22.

Solve for x<br> 20 points
torisob [31]

Answer:

x = 21 units

Step-by-step explanation:

<em>The tangent squared is equal to the secant's total length multiplied by the secant's length without the part inside the circle.</em>

So here, that will look like: <em>36² = 27 * (27 + x)</em>

Expansion and multiplication gives us: <em>1296 = 729 + 27x</em>

Subtract from both sides: <em>567 = 27x</em>

Divide from both sides: x = 21.
