Solve 3(2d-1)-2d=4(d-2)+5

0=0

Step-by-step explanation:

3 (2d -1) -2d = 4 (d-2) +5

6d - 3 - 2d = 4 (d -2) + 5

6d - 3 = 4 (d- 2) +5

4d - 3 = 4 (d - 2) +5

4d - 3 = 4d - 8 + 5

4d -  3 = 4d -3

4d - 3 +3 = 4d -3 +3

4d = 4d - 3 + 3

4d = 4d

4d -4d = 4d -4d

0 = 4d -4d

0 =0

0 = 0

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
