Which is the graph of the system of equations
Y=3x+6 and y=3x+1?

Answer:

15/100 * 450 = 67.5 (discount)

450 - 67.5 = 382.5 (sale price)

7/100 * 382.5 = 26.775 (7% tax)

26.775 + 382.5 = 409.275 (final price)

i am assuming that its a typo and you meant 36

Answer:

Originally, you put 36..but 2nd you put 26... so ill answer both :) for a total of 36 Devery needs to read 11 more pages and for a total of 26, Devery needs to read one page

Step-by-step explanation:

10+15=25   36-25=11

10+15=25   26-25=1

Answer:

9x-3

Step-by-step explanation:

3(2x-1)+3x

The first thing you would want to do is to distribute 3(2x-1) or in other words to get rid of the parenthesis.

3(2x-1) = 6x-3

The expression so far is : 6x-3+3x

Now you would add like terms which are the 6x and 3x = 9x

Expression now: 9x-3

The final answer is 9x-3.

If you are wondering why this is the answer because you can’t solve an (x) from a number because they are not like terms.

Hope this helps!

Answer:

= 43.16

Step-by-step explanation:

1. 83 x 52

2. = 4,316

3. There are 2 numbers after the decimal

4.  you add the decimal the number of times the decimal is away from the number before

Answer:

43.16

Step-by-step explanation:

Look at the attached image. We multiply 83 and 52. Once we get our answer, we move our decimal point two places to the left (since .83 has its decimal moved two places to the left).

Answer:

44

Step-by-step explanation:

44÷5 is 8.8 which is greater than 7

Answer:

x=44

Step-by-step explanation:

Divide each number by 5

-44/5 = -8.8

34/5 = 6.8

44/5=8.8

-34/5=-6.8

8.8 is the only one greater than 7 so 44 is the only one that satisfies the inequality

Answer:

3(3+5)

Step-by-step explanation:

first, you have to find the greatest common factor of 9 and 15, which is 3.

then, you have to do:

9/3 = 3

15/3 = 5

so if you factor out the 3, you get 3(3 + 5)

Answer:

The probability none mechanical engineering majors is 0.03967.

Step-by-step explanation:

Given that,

Total students = 125

Number of students in computer science = 28

Number of students in mechanical engineering = 52

Number of students in civil engineering= 12

Suppose six students from the class are chosen at random what is the probability none are mechanical engineering majors?

We need to calculate the probability none are mechanical engineering majors

Using given data

None mechanical engineering majors = [tex]\dfrac{125-52}{125}=0.584[/tex]

If six students from the class are chosen at random then

The probability none are mechanical engineering majors will be

[tex]P_{nme}=(0.584)^6[/tex]

[tex]P_{nme}=0.03967[/tex]

Hence, The probability none mechanical engineering majors is 0.03967.

Step-by-step explanation:

sin²x = 2 - 2cosx

1 - cos²x = 2 - 2cosx (because sin²x + cos²x = 1)

cos²x - 2cosx + 1 = 0

(cosx - 1)² = 0

cosx - 1 = 0

cosx = 1

Hence x = 0.

Answer:

120ways

Step-by-step explanation:

This question bothers combination. Combination has to do with selection.

Given

Total number of brands = 10

If we the service is to rank the top 3, this can be done in 10C3 number of ways.

10C3 = 10!/(10-3)!3!

10C 3 = 10!/7!3!

10C3 = 10*9*8*7!/7!3!

10C3 = 10*9*8/6

10C3 = 720/6

10C3 = 120

Hence it will take 120ways for the consumer testing service to arrive at the final ranking

Answer:

I believe it is 6 days.

The total number of days all crew needs to pour concrete is 6 days consecutive.

What information do we have?

Total number of crew = 3

Total yards = 175,000

Each crew pour concrete per hour = 1200

Total concrete pour per day = 1200 × 3 × 8

Total concrete pour per day = 28,800 yard

Total number of days crew pours concrete = Total yards / Total concrete pour per day

Total number of days crew pours concrete = 175,000 / 28,800

Total number of days crew pours concrete = 6.076

Total number of days crew pours concrete = 6 days

Answer:

1) [tex]n = 84[/tex]

2) [tex]n = 78[/tex]

3) [tex]n = 24[/tex]

4) [tex]n = 16[/tex]

5) [tex]n = 35[/tex]

Step-by-step explanation:

To solve each proportion, we apply cross multiplication.

Question 1:

[tex]\frac{5}{12} = \frac{35}{n}[/tex]

[tex]5n = 35*12[/tex]

Simplifying both sides by 5

[tex]n = 7*12 = 84[/tex]

Question 2:

[tex]\frac{n}{52} = \frac{180}{120}[/tex]

[tex]120n = 52*180[/tex]

Simplifying both sides by 20

[tex]6n = 52*9[/tex]

Simplifying by 3

[tex]2n = 52*3[/tex]

Simplifying by 2

[tex]n = 26*3 = 78[/tex]

Question 3:

[tex]\frac{18}{n} = \frac{21}{28}[/tex]

[tex]21n = 18*28[/tex]

Simplifying both sides by 7

[tex]3n = 18*4[/tex]

Simplifying both sides by 3

[tex]n = 6*4 = 24[/tex]

Question 4:

[tex]\frac{n}{4} = \frac{24}{6}[/tex]

[tex]\frac{n}{4} = 4[/tex]

[tex]n = 16[/tex]

Question 5:

[tex]\frac{10}{16} = \frac{n}{56}[/tex]

[tex]16n = 56*10[/tex]

Simplifying by 2, both sides

[tex]8n = 56*5[/tex]

Simplifying by 8, both sides

[tex]n = 7*5 = 35[/tex]

The given expressions can be evaluated by using the arithmetic operations in order to find the value of 'n' in each case.

1) 5/12 = 35/n

Cross multiply in the above expression.

5n = 35 [tex]\times[/tex] 12

Further, simplify the above expression.

n = 84

2) n/52 = 180/120

Cross multiply in the above expression.

180n = 120 [tex]\times[/tex] 52

180n = 6240

Divide 180 by 6240 in the above expression.

n = 34.67

3) 18/n = 21/28

Cross multiply in the above expression.

18 [tex]\times[/tex] 28 = 21n

504 = 21n

Divide 504 by 21 in the above expression.

n = 24

4) n/4 = 24/6

Cross multiply in the above expression.

6n = 24 [tex]\times[/tex] 4

6n = 96

Divide 96 by 6 in the above expression.

n = 16

5) 10/16 = n/56

Cross multiply in the above expression.

10 [tex]\times[/tex] 56 = 16n

560 = 16n

Divide 560 by 16 in the above expression.

n = 35
