Tyhir took a total of 16 lessons from Ms. Carter.
Work: 695-55 ( because the question is not asking for recitals). Then you do 640/40. That gives you an answer of 16.
Have a nice day!!!
Answer:
Sometimes they represents the same value
Step-by-step explanation:
the expression x-3 and y-3 represent the same value.
yes sometimes the expression x-3 and y-3 represent the same value.
the expression x-3 and expression y-3 represents the same value only when x=y (that is only when x and y values are same)
For example
when x=5 and y=5
then expression x-3 becomes 5-3= 2
the expression y-3 becomes 5-3=2
so both the expression give same value when x=y
Sometimes they represents the same value
Answer:
discriminant = 0
The real root -2/3
Step-by-step explanation:
The formula for discriminant : b^2 - 4ac
12^2 (-4)×9×4 = 144 - 144 ➡ discriminant = 0 this means the roots is a repeated real number, which means there's only one solution
(3x + 2) × (3x + 2) = 0
3x+ 2 = 0
x = -2/3
Since the 100 degree angle is the same as the m + 20 degree angle, you only have to do: 100-20=80
So the answer is 80
