If ABCD ≅ QRST, then m∠A = m∠Q. Therefore we have the equation:

x - 10 = 2x - 30       |+10

x = 2x - 20     |-2x

-x = -20      |<em>change the signs</em>

x = 20

<h3>Answer: B. 20</h3>

Solve the inequality. 6x + 3 &gt; 3x + 30 A) x &gt; 9 B) x &gt; 11 C) x &gt; −9 D) x &gt; −11
ANTONII [103]

Subtract 33 from both sides

6x>3x+30-36x>3x+30−3

 Simplify 3x+30-33x+30−3 to 3x+273x+27

6x>3x+276x>3x+27

 Subtract 3x3x from both sides

6x-3x>276x−3x>27

Simplify 6x-3x6x−3x to 3x3x

3x>273x>27

Divide both sides by 3

3x>\frac{27}{3}x>

​

3x> ​27

​​  

Simplify \frac{27}{3}

​3
