C) The 2 triangles are similar , then we can write:
5x/45 = 20/36 . Cross multiplication:
5x*36 = 45*20
180x = 900 and x = 900/180 , x = 5 (and 5x = 25)
d) Remember the proportionality theorem (or Thales')
You can write the following proportion:
GH/HJ = KL/LM
8/6 = 10/x . Cross multiplication:
8x = 60 and x = 60/8 , x = 7.5
Answer:
60+80+x=180
Step-by-step explanation:
__ + __ + __ = __ fill in the blanks
if 60, 80, and y have a sum of 180, the equation is 60+80+x=180
if you mean that 3x+3=0 then x should equal 0
They should get $7.50, because you multiply the adults by two, then the children by three, and add it all together
Answer:(3x+7)(x+2)
Step-by-step explanation:
