3(x+1) = 2(x-8) + 3. First, remove the parentheses by distributing (multiplying out the numbers):

3x + 3 = 2x - 16 + 3.

Then, combine any like terms on the same side of the equals sign;

3x + 3 = 2x -13.

Then, move the like terms on opposite sides of the equals sign to the same side of the equals sign (don't forget to change the signs)..

3x -2x = -13 - 3.

Then combine the like terms on the same side of the equals sign again.. x = -16 .

12. Find the value of x. HELP PLS HELP

xenn [34]

Answer:

x = 16

Step-by-step explanation:

SR = ST ⇒ Two sides are equal. So, ΔSRT is an isosceles triangle.

The angles opposite to equal sides are equal.

⇒ ∠STR = ∠R

∠STR = 4x - 28

Linear pair: If a ray stands on a line, then the adjacent angles are supplementary and they are called linear pair

∠STR + ∠STU = 180° {linear pair}

4x - 28 + 9x = 180

4x + 9x - 28 = 180 {Combine like terms}

13x- 28 = 180

Add 28 to both the sides

13x = 180 + 28

13x = 208

Divide both sides by 13

x = 208/13

$\sf \boxed{x = 16}$

Determine the values of the variables in the parallelograms below help me please

PolarNik [594]

Answer:

Part 1)

$x=-11$

$m=170\°$

Part 2)

$x=-5, x=1$

$m=-10, m=14$

Step-by-step explanation:

we know that

In a parallelogram opposite sides and opposite angles are congruent, and consecutive angles are supplementary

Part 1)

Find the value of x

$25=-3x-8$ ----> opposite sides are congruent

solve for x

$25=-3x-8$

$3x=-8-25$

$x=-33/3=-11$

Find the value of m

$(70+(m-60))=180\°$ ----> consecutive angles are supplementary

solve for m

$m=180\°-10\°=170\°$

Part 2)

Find the value of x

$5=x^{2}+4x$ ---> opposite sides are congruent

using a graphing tool

see the attached figure N 1

The solutions are

$x=-5, x=1$

Find the value of m

$(m^{2}-4m)=140\°$ ---> opposite sides are congruent

solve for m

using a graphing tool

see the attached figure N 2

The solutions are

$m=-10, m=14$
