What should the following equation be multiplied by in order to eliminate the fractions?

x/2 + x/3 = 25/3

A. 6
B. 9
C. 5
D. 25

Answers

Answer:

A. 6

Step-by-step explanation:

1. Find the lowest common denominator of the fractions: the lowest common factor of the existing denominators. Here it would be 2 x 3= 6. This is the lowest number that could be the denominator of all of the fractions.

2. Convert all of the fractions so that they have the lowest common denominator.

To do this:

[tex]\frac{x}{2}[/tex] x [tex]\frac{3}{3}[/tex] (equivalent to 1, so doesn't change value of fraction)= [tex]\frac{3x}{6}[/tex]

[tex]\frac{x}{3}[/tex] x [tex]\frac{2}{2}[/tex]= [tex]\frac{2x}{6}[/tex]

[tex]\frac{25}{3}[/tex] x [tex]\frac{2}{2}[/tex]= [tex]\frac{50}{6}[/tex]

3. Now, since all of the fractions have the same denominator (all of the top numbers are divided by the same number on the bottom), then entire equation can be multiplied by this number to eliminate the fractions.

([tex]\frac{3x}{6} + \frac{2x}{6} = \frac{50}{6}[/tex]) x 6 gives us: 3x + 2x=50

4. So, the answer would be A. 6, as this is the number that we multiplied the equation by to remove the fractions.

PLEASE HELPPPPP ME I HAVE SO MUCH TO DO ONLY 2 questions

Answers

Answer:

1)37.68

2) 113.04

Step-by-step explanation:

So for number 1, circumfence is diameter times pi, so diameter is 12 and assuming 3.14 for pi then 12(3.14)=37.68

Number 2, the area of a circle is pi(radius)^2 so we know the diameter is 12 and to find raidus we divide 2 since raidus is half of the diameter, square the radius which is 6^2 which will give you 36, assuming pi is 3.14 multiply 36 by 3.24, 36(3.14)=113.04

I need answer to Y in this math problem and how i can do this problem

Answers

Answer:

,the value of y is 27 degrees.

Step-by-step explanation:

Since the opposite angles of a parallelogram are equal, we know that angle x is also 51 degrees.

Now, we can use the fact that the sum of angles in a triangle is 180 degrees to find the missing angle, which we can label as z.

x + y + z = 180

51 + y + z = 180

y + z = 129

We can also see that angle z and angle 78 form a straight line, so they add up to 180 degrees.

z + 78 = 180

z = 102

Now we can solve for y:

y + z = 129

y + 102 = 129

y = 27

A figure is rotated 180°clockwise, then 90°counterclockwise. Which single rotation is equivalent to this?

Answers

Answer:

90

Step-by-step explanation:

180-90

clockwise-counterclockwise

A single rotation of 90° in the clockwise direction is equivalent to the rotation given.

For the image of a figure to overlap with itself, the amount by which the figure should be rotated is?

For the image of a figure to overlap with itself, the figure should be rotated by 360°

We have a image that is is rotated 180°clockwise, then 90° counterclockwise.

The rotation of the image which is is rotated 180°clockwise first and then 90° counterclockwise can be replaced by a single rotation of 90° in the clockwise direction. Mathematically -

Ф = + 180° + (-90°) = + 90°

Therefore, a single rotation of 90° in the clockwise direction is equivalent to the rotation given.

A car rental company has started renting large motorcycles. The rental fee is $35 a day plus $0.50 per mile. When Nicholas returned his rent ed motorcycle, the odometer read an increase of 452 miles, and his bill totaled $296. For how many days did Nicholas rent the motorcycle?

Answers

At $35 a day and $0.50 pre mile.

You want to take the mileage he went (452 miles) and multiply by cost pre mile ($0.50)

452 x $0.50 = $226 total cost for mileage

His total cost of his bill was $296 so you want to take the total bill cost and subtract the total mileage cost

$296 - $226 = $70

So $70 would divide by $35 a day for the rental

$70 / $35 = 2.

He rented the motorcycle for 2 days.

How do I write an equation for line l in point-slope and slope-intercept form? L is parallel to y=3x

Answers

Answer: y+4=3(x-2)

slope intercept form : y=3x-10

Step-by-step explanation:

The required point-slope and slope-intercept form of the line is y + 3 = 3 (x - 4) and y = 3x - 15 respectively.

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
Given line = y = 3x
The slope of the above line is,
m = 3
Line L parallel to line y = 3 x
so the slope of both lines will be the same,
Now,
The equation line passes through the point (4, -3),
Point slope form of the line,
y - y₁  = m (x - x₁)
y + 3 = 3 (x - 4)
y =3x - 12 -3
y = 3x - 15

Thus, the required point-slope and slope-intercept form of the line is y + 3 = 3 (x - 4) and y = 3x - 15 respectively.

The roots of a quadratic equation are 5 and 2/3. If one of the two factors is x-5, what could be a second
factor?
Explain your reasoning.

Answers

Answer:

Step-by-step explanation:

Given the roots of quadratic equation to be 5 and 2/3, the two factors are x-5 and x-2/3.

The variable in question are both subtracted from the root given to get the actor of the quadratic equation or polynomial. We can get the resulting quadratic function by multiplying both factors together as shown;

(x-5)(x-2/3)

= x²- 2x/3 -5x +10/3

= x²-(2x-15x)/3+10/3

= x²-17x/3 +10/3

Multiply through by 3

= 3x²-17x +10 = 0

The resulting quadratic equation for both factors will be  3x²-17x +10 = 0 and the other factor is x-2/3

For the function f ( x ) = − 2x^2 + 2x + 8 , evaluate and fully simplify each of the following.

f ( x + h ) =

f ( x + h ) − f ( x ) =

Answers

Answer:

[tex]f(x+h)=- 2x^2-4xh-2h^2 + 2x+2h + 8[/tex]

[tex]f ( x + h ) - f ( x )= h(-4x-2h+2)[/tex]

Step-by-step explanation:

Given the function:

[tex]f ( x ) = - 2x^2 + 2x + 8[/tex]

Find

f ( x + h )f ( x + h ) - f ( x )

Recall the identity to square a binomial:

[tex](a+b)^2=a^2+2ab+b^2[/tex]

[tex]f(x+h)=- 2(x+h)^2 + 2(x+h) + 8[/tex]

Squaring the binomial:

[tex]f(x+h)=- 2(x^2+2xh+h^2) + 2(x+h) + 8[/tex]

Multiplying:

[tex]\boxed{f(x+h)=- 2x^2-4xh-2h^2 + 2x+2h + 8}[/tex]

--------------------------------------------------------------

To compute f ( x + h ) - f ( x ), we use the last result:

[tex]f ( x + h ) - f ( x )=- 2x^2-4xh-2h^2 + 2x+2h + 8-(- 2x^2 + 2x + 8)[/tex]

Multiplying:

[tex]f ( x + h ) - f ( x )=- 2x^2-4xh-2h^2 + 2x+2h + 8+ 2x^2 - 2x - 8[/tex]

Simplifying similar terms:

[tex]f ( x + h ) - f ( x )= -4xh-2h^2+2h[/tex]

Factoring:

[tex]\boxed{f ( x + h ) - f ( x )= h(-4x-2h+2)}[/tex]

Note: This expression is commonly used to compute the first derivative of a function by its definition.

Find the circumference of a circle with radius, r = 12m.
Give your answer in terms of π.​

Answers

Answer:

C = 24 pi meters

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

C = 2 * pi * 12

C = 24 pi meters

Answer:

24π

Step-by-step explanation:

The circumference of a circle uses this equation: [tex]2\pi r[/tex]. Just like the last question I answered, you want to give the answer in terms of pi, so we aren't going to multiply pi.

The question gives us the radius so we don't have to divide anything, we plug in r with 12 as is.

[tex]C=2\pi 12[/tex]

Now multiply the 2 and the 12 so it will be in terms of pi.

[tex]C=24\pi[/tex]

In terms of pi, the circumference is 24π.

Tickets to a drama production cost $2.50 for students and $4 for non-students. If 285 tickets were sold
for a total of $1012.50, how many of each kind were sold?

Answers

Step-by-step explanation:

Let the ticket sold to the students be x, and the one sold to the non-students be y.

2.5x + 4y = 1012.50

x + y = 285

2.5x + 4y = 1012.50

2.5x + 2.5y = 285*2.5

1.5y = 1012.5 - 712.5

1.5y = 300

3y/2 = 300

y = 300 *2/3 = 200

x = 285 - 200 = 85

Therefore 200 tickets and another kind of 85 tickets were sold.
