Answer:
7>x
Step-by-step explanation:
First you expand the brackets/parenthesis
9(2x-3) = 18x - 27
12x>18x-27 -15
Collect like terms, so take 15 from -27
-27 -15 = -42
12x>18x - 42
Take the -42 to the other side by adding 42 to both sides
12x + 42>18x
Take 12x from both sides
42>6x
Divide both sides by 6 and you have your answer
7>x
<span>Consider the triangles ERT and CTR.
|ER|=|CT| shown
(</span>Therefore, one can say that segment ER is congruent to segment CT.)
m(R)=m(T)= 90°shown
(By the definition of a rectangle, all four angles measure 90°)
|RT|=|TR|
so we have Side Angle Side congruence.
By the <span>(SAS) Theorem, the triangles are congruent.
