Answer:
y = x - 7
Step-by-step explanation:
You take each equation and sub in for x and y.
The first equation would look like this:
16 = 2(23) - 30 Then you answer looks like this:
16 = 16 but if you did that for the second set in the column it looks like this:
18 = 2(25) - 30
18 = 50 - 30
18 = 20 which does not equal canceling the first answer.
And the second answer doesn't make sense because if x > y you shouldn't add to x. The same goes for the third answer.
So that leaves only one answer y = x - 7
Hope this helps

5*5*5*5*5*5*5
here,
count how many 5 are there - 7
so,
<u>exponential notation form:</u>
5*5*5*5*5*5*5 = 5⁷
Simple way of finding the decimal value : -
=> 46/200
Divide numerator and denominator by 2
=23/100
As 100 is in denominator, shift decimal by 2, i.e
= 0.23
Answer = 0.23
