0.4 multiplied by x would give you the percentage and putting x over 2 would give you half of that number
Answer:
The answer is that x = 0 and y = -6. While this is not any of your options, the work below proves that it is correct.
In order to find these values, we can use elimination. To do so, we multiply the first equation by 5 and then add the equations together.
125x - 5y = 30
-2x + 5y = -30
------------------
123x = 0
x = 0
Now that we have this value, we can plug the value into one of the originals and find y.
25x - y = 6
25(0) - y = 6
-y = 6
y = -6
Answer:
-24
Step-by-step explanation:
If there were 5 transactions, 5 times the mean amount of the transactions will add up -120. If "x" is the mean amount of the transactions:
5*x = -120
x = -120/5
x = -24
The only one I can thing of would be the Number 1
