Ok so first we evalute -2/3*-15 this equals 10
Now we multiply this by 0.25 and add 7, this equals 9.5
Finally we subtract 1/2 which equals 9
(7+0.25(-2/3*-15))-1/2=9
Answer:
213.07 m
Step-by-step explanation:
We need to convert to the same units before subtracting.
The length of Ravi's rope is 214 meters.
If he gave 93 centimeters to his brother, then he didn't give up to a meter.
The reason is that, 100cm makes 1m.
Therefore 93cm makes 0.93m
We now set up the subtraction problem:
Therefore Ravi has 213.07m of rope left.
The answer is: " (y + 3) (y + 2) " .
__________________________________________________
Or, write as: " (y + 2) (y + 3) " .
__________________________________________________
Given: " y² + 5y + 6 " ;
__________________________________________________
we see that:
___________________
we have +5y and +6 ;
___________________
so, the factors 6 that would add up to "5" would be:
___________________________________________
1, 6 = 7 ; no.
2, 3 = 5 ; yes!
3, 2 = 5 ; yes! (same as above).
6, 1 = 7 ; no (same as above).
___________________________________________
So, we have: (y + 3) (y + 2) = y² + 5y + 6 ;
Or ; (y + 2) (y + 3) = y² + 5y + 6 .
