A triangle has sides measuring 2 and 7 of X represents the length in inches of the third side, which inequality gives the range
Nat2105 [25]

Answer:

The inequality range of X is determined as    5 < X < 9

Step-by-step explanation:

Given;

first length of the triangle = 2 inches

second length of the triangle = 7 inches

third length of the triangle = X

From the third length rule of a triangle, the following inequality range will be applied to determine the length of "X";

The third length of the triangle must be greater than the difference of the two known sides BUT less than the sum of the two known sides.

(7 - 2) < X < (7 + 2)

   5 < X < 9

possible values of X = 6, 7, 8

Therefore, the inequality range of X is determined as    5 < X < 9

Solve the following equation for r : (1/t(t-1)) - 1/t = 3/t-1
givi [52]

Domain:\\\\t(t-1)\neq0\to t\neq0\ \vee\ t\neq1

\dfrac{1}{t(t-1)}-\dfrac{1}{t}=\dfrac{3}{t-1}\qquad|+\dfrac{1}{t}\\\\\dfrac{1}{t(t-1)}=\dfrac{3}{t-1}+\dfrac{1}{t}\\\\\dfrac{1}{t(t-1)}=\dfrac{(3)(t)}{t(t-1)}+\dfrac{(1)(t-1)}{t(t-1)}\\\\\dfrac{1}{t(t-1)}=\dfrac{3t+t-1}{t(t-1)}\\\\\dfrac{1}{t(t-1)}=\dfrac{4t-1}{t(t-1)}\iff1=4t-1\qquad|+1\\\\2=4t\to4t=2\qquad|:4\\\\\boxed{t=0.5}

Please help!!! Thanks!
xz_007 [3.2K]

Answer:

x=16

Step-by-step explanation:

angle TVQ = angle VWS (if they are parallel they can be said as corresponding angles)

5x-22 = 3x+10

5x-3x = 10+22

2x = 32

x = 32/2

x = 16
