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

Which number is the best estimate of 866,214,000,000 using powers of 10
a) 9 × 10¹¹
b) 8 × 10¹¹
c) 10 × 11¹⁰
d) 8 × 10-¹¹
Answer:
a) 9 × 10¹¹
Step-by-step explanation:
When we want to estimate a number using the power of 10, we are trying to write the number in a standard form.
We are to estimate :866,214,000,000 using powers of 10
Hence,
8.66214000000 × 10¹¹
We round up to the nearest whole number
= 9 × 10¹¹
Therefore, the best estimate for 866,214,000,000 using powers of 10
= 9 × 10¹¹
Answer:
A) y=2 x
Step-by-step explanation:
<u><em>Explanation:</em></u>-
we will choose equation y =2 x
given data
x : 5 8 9 11
y : 10 16 18 22
substitute x =5 ⇒ y = 2(5) =10
substitute x =8 ⇒ y = 2(8) =16
substitute x =9 ⇒ y = 2(9) =18
substitute x =11 ⇒ y = 2(11) = 22
The data is satisfied the equation y =2 x
The relationship of two variables of the equation is y =2 x
