Answer:

x = -10

Step-by-step explanation:

3(x+1) +5 = 2x -2

<em>Distribute the 3 to the x+1</em>

3x+3 +5 = 2x -2

<em>Combine like terms</em>

3x + 8 = 2x -2

<em>Subtract 2x from both sides</em>

x + 8 = -2

<em>Subtract 8 from both sides</em>

x = -10

Hope this helps!

Answer:

x=-10

Step-by-step explanation:

3(x+1)+ 5=2x- 2

Distribute the 3

3(x+1)+ 5=2x- 2 would equal

3x+3+5=2x-2

Combine like terms

3x+3+5=2x-2

3+5=8 So,

3x+8=2x-2

You want to get the numbers with x on one side

Subtract 8 on both sides to get 3x by itself

3x+8-8=2x-2-8

3x=2x-10

Then you have to get the 2x on the other side because you still want x on the other side so you do -2x on both sides

Which gives you

x=-10

That is your answer

Dafna1 [17]
I would actually use division. So divide 56 by 8, and you'll get 7.

Or you can multiply 7 times 8 and get 56.

Hope this helps!

Solve. 9(4h - 6) = 2( -13 - 2h)
Afina-wow [57]

Answer: h= 7/10

Step-by-step explanation:

9(4h - 6 ) = 2(-13 - 2h)       Distribute on both sides

9(4h) + 9(-6) = 2(-13) + 2(-2h)

36h - 54 = -26 - 4h       Add 4h to both sides

+4h                   +4h

40h - 54 = -26      Add 54 to both sides

      +54     +54

40h = 28     Divide both sides by 40

h = 7/10

Geomtry plz help me 15 pointz
nikitadnepr [17]

Answer:

m∠R=76°

Step-by-step explanation:

∠STR=∠RST=(2x+2)° (base angles of isos triangle)

2(2x+2)+(3x+1)=180 (angle sum of triangle)

      4x+4+3x+1=180

               7x+5=180

                    7x=180-5

                        =175

                      x=175÷7

                        =25

Hence, m∠R = (3x+1)°

                     = [3(25)+1]°

                     = (75+1)°

                     = 76°
