For each equation, find a value x that makes the equation true. (PZZZ help me)

1 x( divided) by 3=12
2 2x+3=20
3 4/3x=10/3
4 -4x=-24
5 2(x-4)=10
6 -0.5x+1.1+2.9

How many roots does the graphed polynomial function have? 1-02

Ranck the following in order from least precise to most precise

Statements reasons 1. ab ≅ cd; ad ≅ bc 1. given 2. ac ≅ ac 2. reflexive property 3. △adc ≅ △cba 3. ? 4. ∠dac ≅ ∠bca; ∠acd ≅ ∠cab 4. cpctc 5. ∠dac and ∠bca are alt. int. ∠s; ∠acd and ∠cab are alt. int. ∠s 5. definition of alternate interior angles 6. ab ∥ cd; ad ∥ bc 6. converse of the alternate interior angles theorem 7. abcd is a parallelogram 7. definition of parallelogram what is the missing reason in step 3?
