Answer:
RX = 12 and XU = 6
Step-by-step explanation:
Given : In ΔTRV , TW ,RU and VS are the medians .
X is the centroid
To Find : RX and XU
Solution:
Since we know that the centroid divides each median in a ratio of 2:1.
Since X is the centroid so RX : XU = 2:1
So, let RX = 2x and XU = x
And we are given that RU = 18
⇒RX +XU=18
⇒2x+x=18
⇒3x=18
⇒
⇒
Thus, RX = 2x = 2*6 =12
XU = x =6
Hence length of RX = 12 and XU = 6
10,000,00 is the correct answer! Since 7 is greater then 5 you would round up to 10 which = to 10,000,000

3(x+2)-9=15-4(5x-2)
First use the distributive property of both sides:-
3(x+2)-9=15-4(5x-2)
3x+6-9=15-20x+8
Now add 20x on both sides:-
23x+6-9=15+8
On simplification,
23x-3=23
Add 3 to both sides:-
23x=26
Divide by 23 on both sides:-
x=26/23
<h3>Good luck.</h3>

Answer:
Step-by-step explanation:
9x+=x-13
9x*3+1/3=x-13
27x+1/3=x-13
27x+1=3(x-13)
27x+1=3x-39
27x-3x=-39-1
24x=-40
x=-5/3
x=-5/3
16 - 4 [ 3 + 2 / (9 - 7)]
16 - 4 [ 3 + 2 / 2)]
16 - 4 [ 3 + 1 ]
16 - 4 [4]
16 - 16
