Answer:
TV = 3x+9 - (14+2x)
TV = 3x + 9 -14 - 2x
TV = x - 5
U = ((3x + 9) + (14 + 2x)) / 2
U = (5x + 23) / 2
TU = (2(3x + 9) / 2) - (5x+23)/2
TU = (6x + 18 - 5x -23) /2
TU = (x - 5) / 2
Since U is the midpt, UV = TU, so UV = (x-5) / 2
TU + UV = TV
(x-5) / 2 + (x-5) /2 = 2 (x-5) /2 = x-5 = TV
Use a number for x. Let's use 10.
T is 39, V = 34
U = (39 + 34)/2 = 73/2 = 36.5
TV = 39-34 = 5
TV from our equation is x-5. 10 - 5 = 5.
TU and UV = (x-5) / 2. (10-5) /2 = 5/2.
(39-34)/2 = 5/2
Ahh I remember doing this but I don't remember clearly. Lemme look for my old notes
Answer:
15 yards
Step-by-step explanation:
use pythagoras theorem
a^2 + b^2 = c^2
9^2 + 12 ^2
81 + 144
225
square root
hypoteneuse= 15 yards
Answer:
a to L is 12 inches and a to n is 32 in Step-by-step explanation:
Step-by-step explanation:
I think you are trying to find x, I dunno, but if you are here's the solution.
when trying to find x, your main goal is to shift all x terms to one side.
For the first one
4x-3 = 5x-3
Carry all x terms to one side:
(4x-3)-5x = (5x-3)-5x
4x-5x-3 = -3
Shift all constants (purely just numbers, no x) to the other side
(4x-5x-3)+3 = (-3)+3
4x-5x = 0
-x = 0
x = 0
The second one:
-2x = 3x-5
5x = -5
x = -1
Done, have fun with math!
