Simplify write without absolute value : |1 + 2x| + |5 − 3x| − |−5x − 8| , is x < −10

3x + 1 – 2x = 9 – 3

Step-by-step explanation:

3) 6 + 2x – 4 = x – 1

4) – 6 – 2x = - 3x – 6

5) x + x +4 +2 = 8

6) 2x + x +5 – 5 = 6

7) 2x – x – 3 – 5 = 2

8) 2x + 2 – 1 – x = 2

9) 5x – 4= 3x – 2

10) 2x – 5 +1 +x = + x – 6

11) – 2x – 5 = 6 – x – 2x

12) – 10 – 4 x + 2x = – 3 – 4x

13) – 5x – 6 + 4 = 4 + 2x – 8x

14) – x = – 6 – 2 – 2x

15) 5x – 10 – 3x +3 + 2x = 20 – x – 4 – 3 + 3x

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
