Answer:
(-∞, -12), (2, ∞)
or
(-∞, -12) U (2, ∞)
Step-by-step explanation:
|3x + 15| > 21, |3x + 15| < -21
3x + 15 > 21, 3x + 15 < - 21
-15 -15 -15 -15
------------------ -------------------
3x > 6 3x < - 36
÷3 ÷3 ÷3 ÷3
------------ ------------------
x > 2 x < -12
(-∞, -12), (2, ∞)
or
(-∞, -12) U (2, ∞)
I hope this helps!
Answer:
The percentage of the guests at this hotel called for room service yesterday is 40%
Step-by-step explanation:
We are given
total number of guests called for room services =170
total number of guests did not called for room services =255

Answer:
6 over 1/24
Step-by-step explanation:
You can find the quotient of 9 2/3 divided by 1 3/5 by first making the two terms into improper fractions.
To make the improper fractions, you can turn 9 2/3 into 29/3 by multiiplying 9 by the denominator (bottom number in fractions) and adding that to the numerator of 2 which gives 29.
1 3/5 can turn into 8/5.
Then you can divide using a simple trick of first organizing the data.
Currentlly it should be
29/3 divided by 8/5
Then you can flip the second fraction over.
29/3 divided by 5/8
Then you change the sign into multiplication.
29/3 times 5/8
Then you multiply like normal.
29 times 5 over 3 times 8
145 over 24
You can simplify now
6 over 1/24
Hope this helps!
