7/12

hope it helps u

Answer: 7/12

Step-by-step explanation:

To add or subtract fractions, first you should make them into LCD (Least Common Denominator). Then, add/subtract the numerator as usual and let the denominator remain.

Solve:

#LCD (Least Common Denominator)

1/3 and 1/4

3 and 4 least common factor is 12

1/3=4/12

1/4=3/12

#Add

 1/3+1/4

=4/12+3/12

=7/12

Answer:

  P = (5, 5)

Step-by-step explanation:

For the given division, ...

  P = (2B +3A)/5

  P = (2(8, 14) +3(3, -1))/5 = (16+9, 28-3)/5 = (25, 25)/5

  P = (5, 5)

_____

For some division ratio of AP : PB = p : q, we have ...

  (P -A)/(B -P) = p/q

  q(P -A) = p(B -P)

  P(p+q) = pB +qA . . . . rearranging

  P = (pB +qA)/(p+q) . . . . . the formula we used above

Answer:

[tex] x = \pm\sqrt{y + 12}[/tex]

Step-by-step explanation:

[tex]y = {x}^{2} - 12 \\ y + 12 = {x}^{2} \\ \pm\sqrt{y + 12} = x \\ x = \pm\sqrt{y + 12} \\ is \: the \: required \: inverse \: function[/tex]

The inverse of the function is given by y = ± √( x² - 12 )

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as A

Now , the value of A is

y = x² - 12   be equation (1)

On simplifying , we get

To calculate the inverse of the function ,

Interchange the value of x with y , we get

x = y² - 12

On solving for y , we get

y² = x + 12

Taking square roots on both sides , we get

y = ± √( x² - 12 )

Hence , the inverse of the function is y = ± √( x² - 12 )

Step-by-step explanation:

The solutions to the system of equations are (2, -1) and (-2,3)

The equations are given as:

[tex](x - 2)^2 + (y - 3)^2 = 16[/tex]

x  + y - 1 = 0

Make y the subject in x  + y - 1 = 0

y = 1 - x

Substitute y = 1 - x in [tex](x - 2)^2 + (y - 3)^2 = 16[/tex]

[tex](x - 2)^2 + (1 - x - 3)^2 = 16[/tex]

Evaluate

[tex](x - 2)^2 + (-x - 2)^2 = 16[/tex]

Expand the equations

[tex]x^2 - 4x + 4 + x^2 + 4x + 4 = 16[/tex]

Evaluate the like terms

[tex]2x^2 + 8 = 16[/tex]

Subtract 8 from both sides

[tex]2x^2 = 8[/tex]

Divide by 2

[tex]x^2 = 4[/tex]

Take the square roots of both sides

x = ±2

Substitute x = ±2 in y = 1 - x

y = 1 - 2 = -1

y = 1 + 2 = 3

Hence, the solutions to the system of equations are (2, -1) and (-2,3)

===========================================================

Explanation:

n = number of nickels

d = number of dimes

Since each nickel is 5 cents, and each dime is 10 cents, we can say

5n = value of all the nickels (ignore the dimes) in cents

10d = value of all the dimes (ignore the nickels) in cents

5n+10d = value of all the coins (nickels+dimes) in cents

5n+10d = 85 is the equation we're after

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

Extra Info:

We don't have enough info to be able to solve for n and d.

The list of all possible solutions are

Note how each time n drops by 2, d goes up by 1.

This is because 2 nickels = 1 dime.

In other words, for every 2 nickels we take away, we add on 1 dime. This works in reverse as well (for every dime removed, add 2 nickels).

The equation to represent the given situation is 5n+10d = 85.

Given that, Andre's coin jar contains 85 cents.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Now, n = number of nickels and d = number of dimes.

Since each nickel is 5 cents, and each dime is 10 cents, we can say

5n = value of all the nickels (ignore the dimes) in cents

10d = value of all the dimes (ignore the nickels) in cents

So equation is 5n+10d = value of all the coins (nickels + dimes) in cents

That is, 5n+10d = 85

Therefore, the equation to represent the given situation is 5n+10d = 85.

Answer: 131°

Step-by-step explanation:

Supplementary angles are the angles that when we add them together, their sum is equal to 180°.

From the question, we are informed that angle w and angle v are supplementary angles and angle v=49.

V + W = 180°

49° + W= 180°

W = 180° - 49°

W = 131°

Answer:

Step-by-step explanation:

As first step we must obtain the equation of the line. According to Analytical Geometry, we can get a equation of the line by knowing two different points. A linear function is represented by the following expression:

[tex]y = m\cdot x + b[/tex]

Where:

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]m[/tex] - Slope, dimensionless.

[tex]b[/tex] - y-Intercept, dimensionless.

If we know that [tex](x_{1}, y_{1}) = (0, 5)[/tex] and [tex](x_{2}, y_{2}) = (3, 8)[/tex], the following system of linear equations is formed:

[tex]5 = 0\cdot m + b[/tex]

[tex]b = 5[/tex] (Eq. 1)

[tex]8 = 3\cdot m + b[/tex]

[tex]3\cdot m + b = 8[/tex] (Eq. 2)

From (Eq. 1) in (Eq. 2) we get the value of [tex]m[/tex]:

[tex]3\cdot m + 5 = 8[/tex]

[tex]3\cdot m = 3[/tex]

[tex]m = 1[/tex]

The equation of the line that contains the points (0, 5) and (3, 8) is [tex]f(x) = x + 5[/tex].

As next step we must apply a reflection in the x-axis, whose operation is defined as follows:

[tex](x', y') \longrightarrow (x, -y)[/tex]

That is:

[tex]x' = x[/tex]

[tex]y' = -y[/tex]

Then, the function [tex]g(x)[/tex] is [tex]g(x) = -x-5[/tex]. We plot each function and include the result in the attachment below.

Answer:

x=10

Step-by-step explanation:

A straight line has an angle of 180 degrees. To solve for x we can add all the given angles and set them equal to 180.

[tex]180= 5x-1+9x+8+2x+13[/tex]

Then combine all the common factors

[tex]180=16x+20[/tex]

And then you can solve for x

[tex]180= 16x+20\\160=16x\\10=x[/tex]

To check if x is correct you can plug in 10 to each equation. If all the equations add up to 180, then x is correct

[tex]5(10)-1= 49\\9(10)+8= 98\\2(10)+13= 33\\\\49+98+33=180[/tex]

Answer:

h = 290 ÷ 7.25, h = 40 u²

Step-by-step explanation:

The formula for the area of a triangle is A = (Bh)/2.

You have already correctly identified the first two steps.

The third step would be to divide 290 by 7.25 to isolate h.

h = 290 ÷ 7.25

= 40 u²

the smallest of the three numbers is 14

Hi there !

three consecutive numbers a ; b ; c

b = a + 1

c = a + 2

a + b + c = 45

replace b ; c

a + (a + 1) + (a + 2) = 45

3a = 45 - 3

3a = 42

a = 42 : 3

a = 14

Good luck !
