Answer:
y=17
Step-by-step explanation:
y=4x+5
change x to 3
y=4(3)+5
y=12+5
y=17
The required value of y is 17 when x=3 for the given equation y = 4x + 5.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
The equation of function is given in the question, as follows:
y = 4x + 5
We have to determine the value of y when x=3 for the above equation.
As per the question, we have
y = 4x + 5
Substitute the value of x = 3 in the above equation,
y = 4(3) + 5
y = 12 + 5
y = 17
Thus, the required value of y is 17.

What is the discount?
What is the sale price?
What is the total price including the 7% sales tax
need help before next semester
Answer:
15/100 * 450 = 67.5 (discount)
450 - 67.5 = 382.5 (sale price)
7/100 * 382.5 = 26.775 (7% tax)

In a class of 125 students, 28 are computer science majors, 52 are mechanical engineering majors, 12 are civil engineers and the rest are general engineering majors. Assume students only have one major. If a student is chosen at random what is the probability they are:
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.
What does 9 + 15 = in distributive property to factor out the greatest common factor?
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)

PIVOT 4A CALABARZON Math G6
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

You work on a concrete crew starting a construction project. Once the pouring begins, it must continue non-stop until it is completed. Your crew will work an 8-hour shift along with two other crews. The total project requires 175,000 yards of concrete. Your supervisor estimates that each crew will pour around 1200 yards per hour. How many consecutive days should you plan to work on this project?
Answer:
I believe it is 6 days.
The total number of days all crew needs to pour concrete is 6 days consecutive.
Work-day based problem: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

sin²x = 2-2cosX
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

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

I need the simplified expression for this please
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!

A consumer testing service is commissioned to rank the top 3 brands of laundry detergent. A total of 10 brands are to be included in the study. In how many ways can the consumer testing service arrive at the final ranking
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
