fenix001 [56]

Answer:

The answer to your question is Yes, he can buy it.

Step-by-step explanation:

Data

Money saved = $35

Original Price = $42

Discount = 30%

Tax = 5 %

Process

1.- Calculate the price of the Video game with the discount

                    $42 --------------------- 100%

                         x  ---------------------   30%

                         x = (30 x 42) / 100

                         x = $ 12.6

   Price with discount = 42 - 12.6

                                    = $ 29.4

2.- Calculate the price of the Video game plus taxes

                      $29.4 ------------------- 100%

                          x      -------------------    5%

                          x = (5 x 29.4) / 100

                          x = 147 / 100

                          x = 1.47

    Price plus taxes = 29.4 + 1.47

                                = $ 30.87

3.- Conclusion

Bruce can buy the Video game because he saved $35 and the video game plus taxes cost $30.87.

How many terms are in the expression shown below?<br> 5x + 3y - 6
MA_775_DIABLO [31]

Answer:

Three terms.

Step-by-step explanation:

Hi there! I'm glad I was able to help you!

Our given expression: 5x + 3y - 6

The equation shown above has three terms. They aren't "like" terms, but altogether we still have three terms.

In mathematical wording, we would call this a TRI-nomial. The prefix "tri" obviously means "three", so this is an easy way to remember the answer!

Term 1: [ 5x ]

Term 2: [ 3y ]

Term 3: [ 6 ]

*** Putting the three terms together makes this a trinomial again! ***

I hope this helped you! You can leave a comment below if you have any other questions! :)

For the peachtree ridge football game 500 students wore blue and 300 students did not. What percent of all the students attendin
Novay_Z [31]
Problem
500 students wore blue and 300 students did not. What percent of all the students attending the game wore blue?

Result
62.5% of all the students attending the game wore blue.

Solution
We can calculate the percent of students wearing blue, after finding the total amont of students, using division and multiplication.
Let's add
500 + 300 = 800

Let's divide

800/500 = 0.625

Let's multiply

0.625 · 100 = 62.5

WILL MARK BRAINLIEST FIRST CORRCET ANSWER
Kazeer [188]

The Venn diagram of each situation is a diagrammatic way of representing what the situation stands for

<h3>How to make the Venn diagrams?</h3>

<u>Diagram 1: A ∩ B ∩ C</u>

This means that we shade all intersection points of the sets A, B and C

<u>Diagram 2: (A ∩ B) ∪ C</u>

This means that we shade the intersection points of the sets A and B and the whole of set C

<u>Diagram 3: A ∩ (B ∪ C)</u>

This means that we shade the where the set A intersects with the whole of sets B and C

<u>Diagram 4: (A ∩ B) \ C</u>

This means that we shade the intersection point of the sets A and B without shading any point on set C

<u>Diagram 5: (A\B) ∪ (B\C) ∪ (A\C)</u>

This means that we shade all set A without set B, all set B without set C and all set A without set C. In other words, we shade everything in the set without shading set C
