84.5 is x because 169 divided by 2 is 84.5. After that you are left with x=84.5. Hope this helps.
Answer:
D) -21.5
Step-by-step explanation:
Answer:
x = 3^11
Step-by-step explanation:
log3(x) =11
Raise each side to the power of 3
3^log3(x) =3^11
This eliminates the log
x = 3^11
Step-by-step explanation:
What this is saying is...20 is a whole number; but 3/4 is not. What they are saying is, if you have to add a mixed number with a whole number, you can add both of the whole numbers together. Then, you add the 3/4 at the end...because it is not a whole number. You can break apart a mixed number by separating the whole number and the fraction.
Hope this helps :)
From y-2x+3=0 we have y=2x-3
So we can replace y by 2x-3 in the equation: 9x+2y=5
And we have 9x+2(2x-3)=5
Or 9x+4x-6=5
and 13x=5+6
Or x=11/13, then y=2x-3= 2. 11/13-3=22/13-3= -17/13
So we have the answer <span>{(11/13, -17/13)}</span>
