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!

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.
Determine whether each quadrilateral is a parallelogram. Justify your answer. Yes/No? Reason... opposite side congruent, opposite angles congruent, opposite sides parallel, diagonals bisect each other, one pair of parallel and congruent sides, not enough information? (look at the image)
Answer:
Yes! The given quadrilateral represents Parallelogram.
Reason: The given quadrilateral has opposite angles congruent.
Step-by-step explanation:
Given the quadrilateral with the angles
118°62°62°118°We know that the sum of the angles of a quadrilateral is 360.
so
118°+62°+118°+62° = 360°
Thus, the given figure is indeed a quadrilateral.
Now in order to determine whether the given quadrilateral is a parallelogram or not, we need to check whether the opposite angles are congruent or not.
If the angles opposite of each other will have the same measurement, then the quadrilateral will represent Parallelogram.
It is clear that the given quadrilateral has two pairs of equal opposite angles.
i.e. The angle 118° has the same opposite angle 118° and the angle 62° has the same opposite angle 62°.
Therefore, the given quadrilateral represents Parallelogram.
Hence,
Yes! the given quadrilateral represents Parallelogram.
Reason: The given quadrilateral has opposite angles congruent.

A hotdog stand sells hot dogs for 2.75 each and drinks for $1.50 each. Each person in a group of n people bought two hot dogs and one drink. Which equation gives y, the total cost in dollars
Answer:
The total cost in dollars, y = $7n.
Step-by-step explanation:
a) Data and Calculations:
Price of hot dogs = $2,75 each
Price of drinks = $1.50 each
Cost of hot dogs bought by one person = 2*2.75 = 5.5
Cost of drinks bought by one person = 1.50
Number of people in a group = n
y = total cost in dollars
y= n($5.5 + 1.50)
y = n * $7
y = $7n
b) Each person's purchase of hot dogs will cost $5.5 (2*2.75). When the cost of hot dogs per person is added to the cost of drinks per person, we have $7 ($5.50 + 1.50). This implies each person will consume hot dogs and drinks worth $7. The total cost will then be $7 multiplied by n, the number of people ($7n).

Answer:
B: 10n⁵ + 11n³ - 6
Step-by-step explanation:
(-3 + 3n⁵ + 6n³) + (7n⁵ + 5n³ - 3)
To add the variables, you can only combine the variables with the same degree.
Because you are adding the polynomials, you can remove the parentheses.
-3 + 3n⁵ + 6n³ + 7n⁵ + 5n³ - 3
Now you can combine the variables that are raised to the same degree.
(-3 - 3) + (3n⁵ + 7n⁵) + (6n³ + 5n³)
Now simplify within the parentheses.
(-6) + (10n⁵) + (11n³)
Now reorder the variables from greatest to least degree.
10n⁵ + 11n³ - 6

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
