Step-by-step explanation:
ratio and proportion
<u> 4 </u> = <u> x </u>
5 2
X multiply:
5x = 4(2)
5x = 8
x = 8 / 5
x = 1 3/5
Answer:
The amount of the bill is dependent on the number of texts sent. Let y be the bill amount and x the number of texts. Then x is independent and y is dependent. This is because x can be any non-negative number, but y depends upon it. You cannot find the bill without knowing the number of text messages, right?
Since you mentioned the fundamental counting principle, I assume you are looking for the total number of possibilities.
If you are picking a month, there are 12 options.
If you are selecting a day of the week, there are 7 options.
If you are doing both, you multiply the two numbers together.
12 x 7 = 84
The rate at which the college student earns credit is 13 credits per semester.
<h3>What is an equation?</h3>
An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario.
Let the credit earned each semester be x.
This will be illustrated as:
5 + 2x = 31
Collect like terms
2x = 31 - 5
2x = 26
Divide
x = 26/2
x = 13
The rate is 13 credits per semester.
