Answer:
the value of x is 7
Step-by-step explanation:
The computation of the value of the x is given below:
Given that
x = 2y - 1...........(1)
2x = 3y + 2.................(2)
Put the equation 1 in equation 2
i.e.
2(2y - 1) = 3y + 2
4y - 2 = 3y + 2
y = 4
So,
x = 8 - 1
= 7
Hence, the value of x is 7
i dont get it...what are the elements of each letter?
Answer:
Step-by-step explanation:
According to the diagram MK is the angle bisector of ∠LMJ in the triangle LMJ.
Use angle bisector theorem, which states:
- <em>an angle bisector of an angle of a triangle divides the opposite side into two parts that are proportional to the other two sides of the triangle.</em>
<em />
Applied to the given triangle, the ratios are:
Use segment addition postulate and substitute known values to get:
- (LJ - JK)/JK = LM/JM
- (14 - JK)/JK = 50/48
- 50JK = 48(14 - JK)
- 50JK = 672 - 48JK
- 50JK + 48JK = 672
- 98JK = 672
- JK = 672/98
- JK = 6.86 (rounded)
To get this you substitute 7 for the x.
7/8(7)-1/2
49/8-1/2
49/8-4/8
45/8 is the value.
(12.1/58.6) × 100 = 20.6484641638%
you can round it to 3 significant figures --> 20.6 %
or to 2 decimal places--> 20.65%
