I need help with geometry.<br> Find x.
I am Lyosha [343]

Answer:

Part 9) x=5  

Part 10) x=-9  

Step-by-step explanation:

we know that

The <u><em>Midpoint Theorem</em></u> states that: The segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side

Part 9) we know that

Point Q is the midpoint segment XY (QY=QX)

Point R is the midpoint segment XW (RW=RX)

Applying the Midpoint Theorem

RQ is parallel to WY

and

RQ=\frac{1}{2}WY  

we have

RQ=2x-3\\WY=x+9

substitute

2x-3=\frac{1}{2}(x+9)  

solve for x                  

4x-6=(x+9)          

4x-x=9+6

3x=15  

x=5  

Part 10) we know that

Point B is the midpoint segment TS (BS=BT)

Point C is the midpoint segment RS (CS=CR)

Applying the Midpoint Theorem

BC is parallel to TR

and

BC=\frac{1}{2}TR  

we have

BC=x+19\\TR=x+29

substitute

x+19=\frac{1}{2}(x+29)  

solve for x

2x+38=(x+29)  

2x-x=29-38          

x=-9

The expression −50x+100 represents the balance, in dollars, of a bank account after x months.
kondor19780726 [428]
Basically get two slopes -50(1)+100 will get you 1,50 (1 is x and 50 is y since its the answer)
-50(0)+100 (0,100)  Y₂-Y₁/X₂-X₁ 50-100/1-0
Rate of change per month = -$50

A family is trying to pick from different shades of paint for their living room. They have narrowed it down to 3 different blues
Olin [163]
To find the denominator:
3+6=9
There are 3 shades of blues so our fraction is 3/9

To get the percent you multiply 3/9×100/1=300/9
300÷9=33.33%
33.33 rounded to the nearest percent is 33%.

Your answer is 33%.
