Answer:

9. x=102

10. x=56

11. x=104

12. x=138

Step-by-step explanation:

9. In this problem, they are alternate exterior angles, meaning they are the same value. x=102

10. x is a corresponding angle, meaning they are the same. x=56

11. There are consecutive interior angles. The sum of these two angles is 180. to find x, subtract 76 from 180. 180-76 = 104 x = 104

12. These two angles are verticle angles, meaning they are equivalent. x = 138

RSB [31]

Answer:

k =4/5

Step-by-step explanation:

$k - 4.8=0.32 - 5.4k\\\mathrm{Multiply\:both\:sides\:by\:}100\\k\times\:100-4.8\times\:100=0.32\times\:100-5.4k\times\:100\\\\Refine\\100k-480=32-540k\\\\Add\: 480\mathrm{\:to\:both\:sides}\\100k-480+480=32-540k+480\\\\Simplify\\100k=-540k+512\\\\\mathrm{Add\:}540k\mathrm{\:to\:both\:sides}\\100k+540k=-540k+512+540k\\\\Simplify\\640k=512\\\\\mathrm{Divide\:both\:sides\:by\:}640\\\frac{640k}{640}=\frac{512}{640}\\\\k=\frac{4}{5}$

Let m stand for number of minutes
.12m+2=25.04
.12m-2=25.04-2
.12m=23.04
.12m÷.12=23.04÷.12
m=192
The number of minutes is 192 minutes.
