Answer:
hello :
2/7y(k-7) = 2/ (7yk-49y)
the expression is equivalent to 2/7y(k-7) is : 2/ (7yk-49y)
valus of k does not equal 0 is : k=7
Answer:
22s - 9
Step-by-step explanation:
The perimeter (P) is the sum of the 4 sides , that is
P = 2s + 7 + 9s - 5 + 6s - 10 + 5s - 1 ( collect like terms )
= (2s + 9s + 6s + 5s) + (7 - 5 - 10 - 1)
= 22s + (- 9)
= 22s - 9
If you can't figure out how to do it, you can always use your answer choices, so for example, use choice a (21 degrees). Plug in 21 for x for both equations. So for the first equation that would be 7(21)-1= 146 and second equation 3(2)-9= 54. Then you would add the results, 146+54=200. In that case, choice 21 is wrong because both of these angles should equal to 180 since it is a supplementary angle. I hope that helped.
ok the answer I think is 7 times because .145x7=565 and if you added another 60 you will be over the budget. I don't know an inequality.
Hope this helps plz give Brainliest plz I need it bad have a nice day.
The answer is -13! Hope this helps!
