Step-by-step explanation:
By AAS congruence, triangles RNM and RNP are congruent. Hence 7x = 2x + 25, x = 5.
Line RM = 7x = 7(5) = 35 units.
Step-by-step explanation:
a.It is a controlled experiment because it is clearly seen that an established hypothesis or study is being verified through an experiment, now in this case the hypothesis is tested through an experiment where excessive stress is placed on the Participants during their math exam to effectively verify that people in urban or city areas live with more stress than people in rural areas.
2..As now that the previously established hypothesis has been verified, it is concluded that people who live in the city live with more anxiety and stress than people who live in rural areas.
x-3(2x-7)=76
distribute
x - 3*2x -3*(-7) =76
x -6x +21 = 76
combine like terms
-5x +21 = 76
subtract 21 from each side
-5x =55
divide by -5
x = -11
We know that the sum of the angles in a quadrilateral all add up to 360 degrees. Here, we know all the angle degrees, just indirectly. To get our answer, we can add up all the given expressions together and make it equal to 360 degrees.
x + (x + 22) + x + (x + 22) + 90 + 90 = 360
Now, combine like terms, the solve for x.
2x + 22 + 2x + 22 + 180 = 360
4x + 44 + 180 = 360
4x + 224 = 360
4x = 136
x = 34
Therefore, the value of x in this problem is 34. Hope this helped and have a great day!
