27) if a = 1/a
multiply both sides by a
a * a = 1/a * a
a^ 2 = 1
Answer is D) 1

6 x 75 = 450
7 x 80 = 560
8 x 85 = 680
9 x 90 = 810
Total all students in class = 6 + 7 + 8 + 9 = 30 students
Total score of whole class:
450 + 560 + 680 + 810 = 2500
Average = 2500 /30 = 83.3 = 83 1/3
Answer is C) 83 1/3
Put 40y and 25.5
Step-by-step explanation:
I js did it lol
The answer to 8+11 is 19 because 8+1 is 9 so 11+8 is 19
6x/6=x>/= (=) 11/6
x=11/6 or about 1.8
the first important notation to remember when graphing inequalities is that the graph is going to face the way the inequality sign is pointing.
in this case, the sign is pointing right. now the second thing to remember is that an inequality sign with a line underneath it means that it is greater/equal to so the graph in which we fill will have be a closed circle
1) start the ray at ~1.8 and fill in the circle at the end of the ray then extend to its endpoint
that's all. you're graph now reads x is greater or equal to 11/6
use a calculator instead of asking
