To solve for C, you have to get both of the numbers with a C on the same side. So, subtract the 5c from the right side onto the left side.

Then, divide by 3 on each side.

So, c = 7.
Answer:
Yes. They are identical triangles which can be seen by the fact that two of their sides are equal. Angle ABC=Angle CBA
Step-by-step explanation:
They are identical isosceles triangles.
Answer: 128.5km
Step-by-step explanation:
Since we are given the information that the distance by road from town A to town B is 257 km. To get 50% of the distance, we simply have to multiply the distance given by 50%. This will be:
= 50% × 257km
= 50/100 × 257km
= 0.5 × 257km
= 128.5km
Therefore, 50% of the distance is 128.5km.
No because irrational cant be a simple fraction and 9/15
is 0.6
so... it is not irrational
