Answer:
-3 < x ≤ 8
Step-by-step explanation:
First, write this statement with symbols:
2x - 5 > -3, but also:
2x - 5 ≤ 11
Adding 5 to both sides of the first inequality yields 2x > 2. pr x > 1.
Adding 5 to both sides of the second inequality results in 2x ≤ 16, or x ≤ 8.
Thus, -3 < x ≤ 8 is the shortest way in which to write the given information.
Answer:
9. 3.93miles
10. 7.42 cm
11. He doesn't have enough money to buy a hat.
12. $10.02
Step-by-step explanation:
9. ⇒
Yesterday walked=1.74 miles
Today walked=2.19 miles
Total walked both days=(1.74+2.19)=3.93miles
10.⇒
Total growth in a month was (12.72-5.3)=7.42 cm
11.⇒
After buying foods, Daniel has (20.39-8.76)=$11.63
The hat is $12
As, 11.63<12 (11.63 is less than 12)
So, he doesn't have enough money to buy a hat.
12.⇒
Penny has $35
Buying a hat and a scarf, Penny has spent (14.99+9.99)=$24.98
Now, Penny will have (35-24.98)=$10.02
Hope, this helps you.
Answer:

Step-by-step explanation:
<em>Standard form</em>, also called <em>scientific notation</em>, is a more compact way of writing very big or very small numbers. All numbers in scientific notation have the form

where m is a number between 1 and 10, and b is an integer that represents how we've shifted the decimal point from the original number. For example, the number 23,000 in standard form would be written as 2.3 × 10⁴, since we have to shift the decimal point 4 places to the right to get back our original number.
We can turn 5,976,000,000,000,000,000,000,000 into a number between 1 and 10 by shifting the decimal 24 places to the left, giving us 5.976. We'll save that 24 as the exponent for our 10, giving us the final form
