Best ResponseYou've already chosen the best response.0the little red lines on AB and BC

Best ResponseYou've already chosen the best response.0the red ticks indicate that AB and BC are equal in length so if AB = 80 you have your answer. This is standard for any problem so commit it to memory; if there are more then one set of lines with same lengths they are indicated with two tick marks each for second set etc.

Best ResponseYou've already chosen the best response.0oh. When you see a "hash mark" like those, it means the two line segments are the same length

Best ResponseYou've already chosen the best response.0so you should think: from A to B is some distance. and from A to C is twice the distance from A to B

Best ResponseYou've already chosen the best response.0Okay so it would be 160

Best ResponseYou've already chosen the best response.0now you need to read what they told you. what did they tell you ?

Best ResponseYou've already chosen the best response.0do you see the question: if AC is 80 ... that means the distance from A to C is 80 (inches, miles, whatever) they want to know A to B we know AB + BC = AC (the two halves add up to the whole)

phi

Best ResponseYou've already chosen the best response.0For Q6, if AB is 28, then BC is what ?

phi

Best ResponseYou've already chosen the best response.0it is the same picture and the same idea

phi

Best ResponseYou've already chosen the best response.0AB and BC are the same size (that is what the red lines mean)

Best ResponseYou've already chosen the best response.0So they are both 28?

phi

Best ResponseYou've already chosen the best response.0they say BC is also 3x+7 so if BC =28 and BC= 3x +7 we can say 3x+7= 28 can you "solve for x" ?
