Answer: 1:50
The scale factor is 5/250 = 1/50
2 slices
If you take the 1/4, and the 8 (which can be re written as 8/1), and multiply them together, you get two.
1/4*8/1=2
8/7 exact form
or
1 1/7 mixed number form
What you must do for this case is to rewrite the first expression to find its value.
We have then:
153 = 2 (z + z) n
Rewriting:
153 = 2n2z
Then,
2n (2z) -193
Substituting
153-193 = -40
Answer:
the value of 2n (2z) -193 is
-40
