Answer:
Step-by-step explanation:
2/3 * 8/3 (reciprocal)
(2*8)/(3*3)=16/9=1 7/9
Answer:
Step-by-step explanation:
+6x-5=0
we divide the coefficient of the X by half :
in this case: 6/2 = 3 , then we do the following
The result obtained is raised to square power: 3^2=9
we sum and subtract by 9 to maintain the balance of the equation:
+6x+9-9-5=0
we have:
-9-5=0
= 14
lets apply square root on both sides of the equation:
we know:
so we have:
abs(x+3)=
from where two solutions are obtained
finally we have:
It took Mark 2 1/2 hours to cycle 25 miles. 2 hours 30 minutes or 150 minutes.
Answer:
Step-by-step explanation:
[logical equivalence]
[morgan laws]
if is true, then is true and is too.
with true, then is false [double denial]
In the first equivalence it follows that is true [identity law]
Then it can be concluded that
First, you must add the total of Monday amd Tuesday
4.32+6.86=11.18
Then you subtract the totals from this week and last week
11.18-7.89=3.29
3.29 rounds to 3.30 aka 3.3 so your answer is C
