Answer:
5.4
Step-by-step explanation:
The equations are equal so set them equal to each other and solve
Answer:
The answer is 75 and 85.
Step-by-step explanation:
If the instrument measures in units of 10, then the measurement could be 5 units on either side of 80 (80 − 5 = 75, 80 + 5 = 85). Any value between 75 and 85 would be measured as 80.
It legally recognised the belligerent status of the Confederate States of America (CSA) but never recognised it as a nation and neither signed a treaty with it nor ever exchanged ambassadors.
And i could tell that its not math... :)
Its False
Sajia can sell 21 books she can sell if she comes back on sunday and the required inequality is ![9 + x \leq 30](https://tex.z-dn.net/?f=9%20%2B%20x%20%5Cleq%2030)
<em><u>Solution:</u></em>
Given that Sajia has 30 Books in her library
She sold 9 books at the thrift store on Saturday
To find: We have to write and solve an inequality to determine number of more books she can sell if she comes back on sunday
Let "x" be the number of more books she can sell if she comes back on sunday
<em><u>We can write a inequality as:</u></em>
![\text{ books already sold } + \text{ number of books remaining } \leq \text{ total number of books she has }](https://tex.z-dn.net/?f=%5Ctext%7B%20books%20already%20sold%20%7D%20%2B%20%5Ctext%7B%20number%20of%20books%20remaining%20%7D%20%5Cleq%20%5Ctext%7B%20total%20number%20of%20books%20she%20has%20%7D)
![9 + x \leq 30](https://tex.z-dn.net/?f=9%20%2B%20x%20%5Cleq%2030)
Now moving 9 from L.H.S to R.H.S we get,
![x \leq 30 - 9](https://tex.z-dn.net/?f=x%20%5Cleq%2030%20-%209)
On solving 30 - 9 = 21,
![x \leq 21](https://tex.z-dn.net/?f=x%20%5Cleq%2021)
So Sajia can sell 21 books she can sell if she comes back on sunday
