Hello,
(9*140-180)/8=147.5

Answer:
Step-by-step explanation:
If M is the midpoint of AB, then AM = MB
Also AM+MB = AB
MB+MB = AB
2MB = AB
2MB = 6
MB = 6/2
MB = 3 cm
Also
If M is the midpoint of CD, then CN = DN and CN+DN = CD
CN+CN= CD
2CN = CD
2CN = 6
CN = 6/2
CN = 3 cm
Note that MN = MB + BC + CN
Substitute the given data
MN = 3cm + 6cm+3cm
MN = 12cm
Therefore the distance between M and N is 12cm
Answer:
x = 17
Step-by-step explanation:
Given equation:
(6x + 3) + 75 = 180
Subtract 75 from both sides:
⇒ (6x + 3) + 75 - 75 = 180 - 75
⇒ 6x + 3 = 105
Subtract 3 from both sides:
⇒ 6x + 3 - 3 = 105 - 3
⇒ 6x = 102
Divide both sides by 6:
⇒ 6x ÷ 6 = 102 ÷ 6
⇒ x = 17
