Hello.
the line segment is 36 cm and the distance between the midpoints of the first and the fourth parts is 30 cm, this means that the sum of the lengths of the first and the last part is
2(36 - 30) = 2(6) = 12 cm.
Thus, the sum of the length of the second and the third part is 36 - 12 = 24 cm.
Therefore, the distance between the midpoints of the second and the third parts is 24 / 2 = 12 cm.
Have a nice day
Answer:
x = -2
Step-by-step explanation:
6(x+7)=30
6x+42=30
6x=-12
x=-2
For this case we must find the solution of the following equation:

Applying distributive property on the right side of the equation we have:

Subtracting 7x from both sides of the equation:

Subtracting 20 from both sides of the equation:

Different signs are subtracted and the major sign is placed.

Dividing between -2 on both sides of the equation:

Thus, the solution of the equation is
Answer:

Answer:
x=1.4
Step-by-step explanation:
Write the equation

Multiply both sides by x

Divide both sides by 4
