Answer:
C. In y^2-y=6, 6 should have been subtracted on both sides first.
Step-by-step explanation:
It is a quadratic equation so you subtract the 6 and create
y^2-y-6=0
Then you factor it to:
(y-3)(y+2)=0
The solutions then are:
y-3=0, y=3 and y+2=0, y=-2
{-2,3}
Answer:
B
Step-by-step explanation:
supplementary angles =180 degrees
180-117=63
613,001,350,283.............
We know that
38% of the incoming students own both a smartphone and a tablet
84% of the students own a smartphone
We are asked to find the percentage of students who own a smartphone
Let N be the total number of incoming students and S be the total number of students
So,
(N (38%) + S (84%)) / (N + S)
If we know the total number of students or incoming students, we can solve for the percentage by substituting the value of N or S
