Answer:
22 hours
Step-by-step explanation:
So, 143 equals eleven hours. 143 plus 143 would equal 243. So, you have two 143s which means you should multiply the 11 hours by two. 11x2 equals 22.
X=4, first you distribute the 2 to both 4x and -11 which leaves you with 8x-22+9=19 next you add -22 with 9 which leaves you -13 the eqation now at 8x-13=19 so now you add 13 to both sides now youre left with 8x=32. Now the last step is to divide 8 on both sides. so that gives you the answer or X=4
Answer:
No.
Step-by-step explanation:
To determine if (0,0) is a solution to the inequality, substitute 0 for x and 0 for y and check to see. Thus:

Substitute 0 for x and 0 for y:

Multiply:

Subtract:

So, (0,0) is <em>not</em> a solution.
And we're done!
Answer:
rounded to the nearest whole number = 166
Step-by-step explanation:
Add all of the angles together, to get 39x. In a hexagon, all the angles add up to 720. Divide 720 by 39 to get x, then multiply x by 9, as that is the largest angle to get an answer rounded to the nearest whole number of 166.
