Two students share 3 granola bars equally. How many granola bars does each student get?

Answers

Answer:

Hence, number of granola bars each get:

1.5 bars

Step-by-step explanation:

It is given that:

Two students share 3 granola bars equally.

This means that 3 bars is to be distributed among 2 students.

Number of students=2.

Number of bars=3.

Hence,

Number\ of\ quantity\ each\ get=(Number\ of\ granola\ bars)/(Number\ of\ students)

Hence,

Number\ of\ quantity\ each\ get=(3)/(2)=1.5

Hence, number of granola bars each get:

1.5 bars
Each student receives one and a half granola bars.

Evan buys 2 CDs. $1.49 is added to the total price which is the 5% sales tax. What is the cost for each of the CDs?

Answers

In the given question, there are several information's that are of great importance. It is by using these information's the correct answer can be determined. It is already given that the amount of sales tax is $1.49 and the percentage of sales tax is 5%. Now it is important to firstly determine the total price of 2 CDs and then determine the price of 1 CD.
Let us assume that the cost of 2 CDs = x
Then
5x/100 = 1.49
5x = 1.49 * 100
5x = 149
x = 149/5
   = 29.8
So the cost of 2 CDs is $29.8.
Now
The cost of each CD = (29.8/2) dollars
                                   = 14.9 dollars
So the cost of each CD is $14.9.

Find the value of x in the equation

Answers

Answer: 10.5 (equivalent to the fraction 21/2)

To get this answer, you set 10x-15 equal to 90 and solve for x. The reason why these two angles are equal is because they are vertical angles.

10x-15 = 90

10x-15+15 = 90+15 ...... add 15 to both sides

10x = 105

10x/10 = 105/10 ...... divide both sides by 10

x = 105/10

x = 21/2 is the answer in fraction form

x = 10.5 is the answer in decimal form

You'll use what the vertical angles theorem tells you to solve this.

The vertical angles theorem says that vertical angles are congruent, which is what the angle with (10x-15) and the opposite angle (90) are.

Since they are vertical angles, they are congruent so you can set up an equation where they are equal and solve for x.

(10x-15) = 90

1. Get rid of the parentheses.

10x-15 = 90

2. Add 15 to both sides.

10x = 105

3. Divide both sides by 10.

x = 10.5

Answer is:

x = 10.5
