Answer:

x = -12/14 is the required solution for the given expression.

Step-by-step explanation:

Here, the given expression is:

5 – 6 x  = 8 x + 17

Now, here solving the expression for the value of x, we get:

5 – 6 x  = 8 x + 17

⇒ 5 -  17   = 8 x +  6 x

⇒- 12  = 14 x

or, x  = -12 / 14

Hence, x = -12/14 is the required solution for the given expression.

Answer: -6/7

Step-by-step explanation:

5 - 6x = 8x + 17

<u>-5                 -5</u>  <= subtract 5 from both sides

-6 x = 8x + 12

<u>-8x    -8x  </u><= subtract -8x from both sides to isolate the variable

<u>-14x</u> =<u> 12</u>

-14     -14 <= divide by -14 to factor out and isolate x

-12/14 can be simplified to  -6/7

Answer:

28. m<A=20°, m<B=70°

32. m<A=103°, m<B=77°

Step-by-step explanation:

complementary angle=a+b=90°

supplementary angle=a+b=180°

28. A+B=90°

      5x+17x+2=90°

      22x+2=90°

      22x=90-2

      22x=88

        22x/22=88/22

      x=88/22=<u>4</u>

m<A=5x=5*4=<u>20°</u>

m<B=17x+2=17*4+2=68+2=<u>70°</u>

         <u>Check</u>

A+B=90°

20+70=90°

<u>90°=90°</u>

32. A+B=180°

     x+11+x-15=180°

     2x-4=180°

     2x=180+4

     2x=184

     2x/2=184/2

     x=184/2

     x=<u>92</u>

m<A=x+11=92+11=<u>103°</u>

m<B=x-15=92-15=<u>77°</u>

     <u>Check</u>

A+B=180°

103+77=180°

<u>180°=180°</u>
