Answer:

Larger number = 11

Smaller number = 6

Step-by-step explanation:

Let the larger number = x

Let the smaller number = y

x - y = 5

3y + 4 = 2x       Subtract 2x

-2x + 3y + 4 = 0

===========

Multiply  the first equation by 2. Write the second equation underneath

2x - 2y = 10

-2x + 3y + 4 = 0

add

y + 4 = 10  

Subtract from both sides

y = 10 - 4

y = 6

==========

x - y = 5

x - 6 = 5                Add 6 to both sides

x = 5 + 6

x = 11

Answer:

Step-by-step explanation:

x       ← the smaller number

x+5    ←  five more than the smaller number - the larger number

3x    ← three times the  smaller number

3x+4   ← four more than three times the  smaller number

2(x+5)   ← twice the larger number

3x + 4 = 2(x + 5)

3x + 4 = 2x + 10

   -4         -4

     3x = 2x + 6

  -2x       -2x

      x  =  6

x+5 = 6 + 5 = 11

Check:   3•6 + 4 = 22;  22:2 = 11

Answer:

(2.666667, -2)

Step-by-step explanation:

y+2 = -3x+12

(-4 times -3 = positive 12)

subtract 2 from both sides

y=-3x-10

-2=-3x-10

add ten to both sides

8=-3x

8/-3=

Answer:

RS = 14

Step-by-step explanation:

Perimeter = 26 + 26 + PT + RS

We know that PT and RS are equal to each other so I changed the equation to 26 + 26 + x + x = 10 + 5x and then I got x by itself and the integer on one side 42 = 3x, so 14 = x

The value of RS will be 14 for the given parallelogram.

A basic quadrilateral with two sets of parallel sides is known as a parallelogram.

A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.

There are 4 types of parallelograms, including 3 special types. The four types are parallelograms, squares, rectangles, and rhombuses.

Given the parallelogram where TS ║ PR and both are equal

Line TP ║ SR so it means TP = SR

Let's say

TP = SR = x

Now,

The perimeter of a parallelogram is 10 more than 5(RS)

So,

PT + TS + SR + RP = 5(RS) + 10

Now since TP = RS = x

So,

x + TS + x + RP = 5x + 10

5x - 2x = TS + RP - 10

x =  (TS + RP - 10)/3

Now,

TS = RP = 26

So,

x = (26 + 26 - 10 )/3

x = 42/3

x = 14

Hence "The value of RS will be 14 for the given parallelogram".

Symmetric Property

Step-by-step explanation:

Symmetric Property, because it tells that the both sides of the equal sign are actually equal,  regardless of which side of the equal sign.

If [tex]x = y[/tex], then [tex]y = x[/tex].

Step-by-step explanation:

Let's make the number we're finding to be [tex]a[/tex]. So, it says that it will be divided by 4 and then added by 12 if we want this in algebraic expression it will be [tex]\frac{a}{4} +12\\[/tex]. It's also telling us that that expression is the same thing as our number divided by 3 and subtracted by 5. If we want an expression out of it it well be [tex]\frac{a}{3} -5\\[/tex]. Since they are the same, we have the equation below.

[tex]\frac{a}{4} +12 = \frac{a}{3} -5\\[/tex]

All we have to do now is to find [tex]a[/tex].

[tex]\frac{a}{4} +12 = \frac{a}{3} -5 \\ \frac{a +48}{4} = \frac{a -15}{3} \\ (3)(a +48) = (a - 15)(4) \\ 3a +144 = 4a -60 \\ (60 -3a) + 3a +144 = 4a -60 +(60 -3a) \\ a = 204[/tex]

7.alternate interior

x=64

8. same side interior

x=12

same side exterior

x=12

Answer:

Step-by-step explanation:

7. alternate angle or opposite angle are equal

   128 = 2x

    x = 128 / 2

    x = 64

8.  interior angles = 180

    180 = 72 + (7x + 24)

    180 - 72 - 24 = 7x

     x = 84 / 7

     x = 12

9.   same side angle = 180

     180 = 65 + (11x - 17)

     180 - 65 + 17 = 11x

     x = 132 / 11

Given:

Four equations are

[tex] 7 x + 1 = 7 x+ 1[/tex]

[tex]3 x + 2 = 3 x-2[/tex]

[tex]4 x + 1 = 3 x + 8[/tex]

[tex]-2x-1 = -2 x-1[/tex]

To find:

Without solving which equation has no solution.

Solution:

We know that, in an equation

1. No solution : When variable terms are same but constants are different.

2. Unique solution : When variable terms are different.

3. infinitely many solution : When variable terms and constants are same.

In first and fourth equations, terms on left sides are equal to the terms on the right side. So, LHS = RHS for any value of x.

Therefore, these two equations (first and fourth) have infinitely many solutions.

In second equation, variable terms are same on both sides, but the constants are difference. So, LHS ≠ RHS for any value of x.

Therefore, the second has no solutions.

In third equation, coefficient of x are difference on both sides.

So, this equation has unique solution.

Therefore, Jubal's equations [tex]3 x + 2 = 3 x-2[/tex] has no solution. Hence, the correct option is B.

Step-by-step explanation:

Given,

LP = 15, PR = 9

Point P lies on the line segment PR. It would mean that,

LP + PR = LR

⇒LR = 15 + 9

⇒ LR = 24

Hence, "LR = 24 because LP + PR = LR according to the Segment Addition Postulate, and 15 + 9 = 24 using substitution" is the correct option.
