Answer:
Yes
Step-by-step explanation:
To figure out if (1,2) is a solution to the system, we can plug the values in and see if it is true.
3x-2y=-1
3(1)-2(2)=-1
3-4=-1
-1=-1
It is true for this equation. Now let's check the next one.
y=-x+3
2=-(1)+3
2=2
Since both equations are true when we plug the values in, (1,2) is a solution to the system.
Answer:
i = 45% and ii = 47% (Rounded)
Step-by-step explanation:
Simply divide 27 by 60 to get i:
27/60=.45
Convert to a percent chance.
.45=45%
Then divide 395 by 840 to get ii:
395/840=.47
Convert to a percent chance.
.47=47%
