Equation Form:
w x 2 19
Divide both sides by 2:
w 9.5
So, w must be equal to or greater than 9.5 for this equation to work.

Yes! he passed
Step-by-step explanation:
The answer is 15000
3000*6=1800
3000*-2=-6000
18000-6000=12000
12000+3000=15000
3000*6=1800
3000*-2=-6000
18000-6000=12000
12000+3000=15000
Given that:
Consider it is instead of 10 on two places.
is between 3 and 4. So, Beau thinks a good estimate for
is = 3.5.
Solution:
To find , Beau found 3² = 9 and 4² = 16.
He said that since 10 is between 9 and 16.
Since 10 is close to 9, therefore must be close to 3. So, Beau's estimate is high.
Now,
Since, 10 lies between 9.61 and 10.24, therefore must be lies between 3.1 and 3.2.
Therefore, the estimated value of is 3.15.
