Step-by-step explanation:
All that you are doing is trying to fiigure out the Frequency of all the tally marks!!
We have,
x+y:x-y=3:2
To prove that, x+ y : x - y = 3:2.
x+y=3
And,
x+y = 2
Adding (1) and (2), we get
x+y+x-y=3+2
⇒2x=5
⇒ x =
Put x = in (1), we get
+y=3
⇒ y=3-=
x+y:x-y=
=3:2
So, x+y:x-y=3:2.
It's 0.720. you just divide 103 and 143 and get the first three numbers
X=10 the two triangles are the same size just one is scaled down by 1/2. Hope this helps
