Answer:
360 and 60.
Step-by-step explanation:
Let Christopher earns x amount of money and y be money earned by Michael.
Firstly, Christopher has six times as much money as Michael so,
x=6y........ (i)
If Michael earns $80 and Christopher earns $60, Christopher will then have three times as much money as Michael so,
x+60=3(y+80)
From (i),
6y +60= 3(y+80)
3(2y+20)=3(y+80)
2y+20=y+80
2y-y=80-20
y=60
Substituting value of y in equation (i),
x=6×60=360.
Therefore, Christopher earned 360 and Michael earned 60.
Answer: Positive
Step-by-step explanation: It would be positive because the question is asking how much money they lost. The lost a positive amount of money.
The two equations given are:
3y + 2z = 12
y - z = 9
Now let us take the second equation first and find the value of y in relation to z
y = 9 + z
Now we will put the value of y found from the second equation in the first equation.
3y + 2z = 12
3(9 + z) + 2z = 12
27 + 3z + 2z = 12
5z = 12 - 27
5z = -15
z = -(15/5)
= -3
Now again we will put the value of z in the second equation for finding the value of y
y = 9 + z
= 9 - 3
= 6
So we find the value of "y" is 6 and that of "z" is -3
Answer:
A=300
Step-by-step explanation:
995-165=830
830+795=1625
1625-1200=425
425-125=300
