Answer:
23/2
Step-by-step explanation:
first turn the mixed number into a fraction:
2*10=20
20+3=23
so, we get 23/2
Wouldn't r = -10?
because you'd multiply -7 by 3, to get rid of the division.
then you'd add 11.
It’s 0
-2 squared is 2 times (-1/2) is -2
8 / -2 squared is 2
So 2+-2 = 0
X = 9/7.
9/x + 9/x = 14
18/x = 14
18 = 14x
18/14 = x
9/7 = x
