Can someone please help me???

Answer:

Luis tiene 30 años de edad y su amiga tiene 20 años edad.

Step-by-step explanation:

Cuando Luis tenia 20 años de edad (hace 10 años), su amiga tenia solamente 10 años de edad. Si multiplicamos 10 x 3 nos da como resultado 30, que es la edad actual de Luis.

L + A = 50

3(A - x) = L

L = 50 - A

3A - 3x = 50 - A

4A = 50 + 3x

en este punto podemos probar diferentes alternativas para x:

x = 5, entonces 4A = 50 + 15

A = 16.25 no es factible porque estamos buscando numeros enteros

x = 6, entonces 4A = 50 + 18

A = 17

al reemplazar, nos da una edad de 3(17 - 5) = 36 para Luis, pero 36 + 17 = 53

x = 8, entonces 4A = 50 + 24

A = 18.5 no es factible porque estamos buscando numeros enteros

x = 10, entocnes 4A = 50 + 30

A = 20

al reemplazar, nos da una edad de 3(20 - 10) = 30 para Luis, y 30 + 20 = 50

Answer:

65/66

Step-by-step explanation:

Find the reciprocal of the second number (11/13), which you find by flipping the top and bottom number so it would be 13/11. Now multiply the top two numbers which are 5 and 13, that equals 65. Multiply the bottom numbers, 6 and eleven which is 66. That is how you get 65 over 66.

Answer:

65/66

Step-by-step explanation:

5/6 * 13/11 = 65/66

Answer:

Answer:

[tex]y=\frac{5}{6}x-2[/tex]

Step-by-step explanation:

Let the equation of a line passing through a point [tex](x_1,y_1)[/tex] and slope [tex]m_1[/tex] is,

[tex]y-y_1=m_1(x-x_1)[/tex]

Equation of the second line has been given as,

6x + 5y = 10

Slope-intercept form of the equation will be,

5y = -6x + 10

y = [tex]-\frac{6}{5}x+10[/tex]

Here slope of the line [tex]m_2=-\frac{6}{5}[/tex]

If both the lines are perpendicular,

By the property of perpendicular lines,

[tex]m_1\times m_2=-1[/tex]

[tex]m_1\times (-\frac{6}{5})=-1[/tex]

[tex]m_1=\frac{5}{6}[/tex]

Therefore, equation of the line passing through (6, 3) and slope = [tex]\frac{5}{6}[/tex] will be,

y - 3 = [tex]\frac{5}{6}(x-6)[/tex]

y = [tex]\frac{5}{6}x-5+3[/tex]

[tex]y=\frac{5}{6}x-2[/tex]

The remainder when 73,847 is divided by 43 will be 16.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The mathematical expression is,

''73,847 is divided by 43''

Now,

Find the remainder when 73,847 is divided by 43 as;

43 ) 73,847 (1717

    - 43

   --------

      308

    - 301

     -------

          74

          43

        -------

          317

        - 301

         ------

           16

Thus, The remainder when 73,847 is divided by 43 will be 16.

The asnwer is 3x + 12y + 4

Answer:

I think you wrote it wrong but if not here

Step-by-step explanation:

Simplifying

2x + -12y = 4

Solving

2x + -12y = 4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '12y' to each side of the equation.

2x + -12y + 12y = 4 + 12y

Combine like terms: -12y + 12y = 0

2x + 0 = 4 + 12y

2x = 4 + 12y

Divide each side by '2'.

x = 2 + 6y

Simplifying

x = 2 + 6y

x=2 is a solution of equations -2(x – 4) = 4 and 26/x=13

Two or more expressions with an Equal sign is called as Equation.

-2(x-4)=4

-2(2-4)=4

4=4

Hence, x=2 is the solution

26/x=13

Now x=2

26/2=13

13=13

Hence, x=2 is the solution

-3.8x=-7.4

Now x=2

-3.8×2=-7.4

-7.6=-7.4

x=2 is not a solution of -3.8×2=-7.4

4(x - 1) – 3(x - 2) = -8

4(2-1)-3(2-2)=-8

4=-8

x=2 is not a solution of -3.8×2=-7.4

Hence, x=2 is a solution of equations -2(x – 4) = 4 and 26/x=13

Ratio problem, we are going to use the part to all approach

Step one:

given data

the ratio of peanuts to other nuts is 6 to 5

otherwise expressed as 6:5

the total ratio is 6+5= 11

the total number of peanut is 414

let the other nuts be x

6/5=414/x

cross multiply we have

414*5= 6x

2070=6x

divide both sides by 6

Answer:

0.4% of the people had a mild allergic reaction.

Step-by-step explanation:

You can find the percent of the people that had a mild allergic reaction using a rule of three as you know that 9,000 people tried the new shampoo which would be the 100% and you can find the percent that represents 36 people:

9,000 → 100%

  36    →   x

x=(36*100)/9,000

x=0.4%

According to this, the answer is that 0.4% of the people had a mild allergic reaction.

Answer: The highest recorded temperature was 38 degrees.

Step-by-step explanation:

Given: The coldest temperature last December was –18.24 degrees.

Difference between this and the highest recorded temperature=

56.24 degrees

The highest recorded temperature = coldest temperature + difference

= -18.24+56.24 degrees

= 38 degrees

Hence, the highest recorded temperature was 38 degrees.

Answer:

3

Step-by-step explanation:

You would first plug in the points to the slope formula which is as follows:

m = y2 - y1 / x2 - x1

When you plug it in, it should look as follows:

m = 10 - 4 / 7 - 5

You should now add like terms.

m = 6/2

You should now simplify.

m = 3

Step 1: We need to first find the equation of the line in slope-intercept form by finding b, or the y-intercept.

[tex]-6 = 3(-5) + b\\\\-6 = -15 + b\\\\9 = b[/tex]

Step 3: We now need to write the equation of the line in slope-intercept form.

[tex]y = 3x + 9[/tex]

Step 3: Now we convert the above equation from slope-intercept form to standard form.

[tex]y = 3x + 9\\\\-3x + y = 9\\\\-3x + y - 9 = 0[/tex]

Our equation in standard form is: B. -3x + y - 9 = 0.
