Answer:
x = 23
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
= 
= 3
multiply both sides by (x - 10)
3(x - 10) = 39 ( divide both sides by 3 )
x - 10 = 13 ( add 10 to both sides )
x = 23
Answer:
We would need pictures of the figures first :(
You know you are finished dividing when you can no longer simply & when you plug it back in to check the answer
Answer:
here p=0.65 and n=100 hence standard error =(p*(1-.
Step-by-step explanation:
That's the associative property of addition
it is normally written as
(a+b)+c=a+(b+c)
which is like what you have
(17+4)+9=17+(4+9)
