Answer:
288
Step-by-step explanation:
24 = 8 1/3 % of x
24 = (25/3 * 1/100)x
25/300 x = 24
x = 24 * 300/25
x = 7200/25
x = 288
Answer:
There will be

Number of text messages sent in the month of November
billion.
Rounding to the nearest tenth the answer will be
billion.
So
billion text messages were sent or received in November.
For this case we must indicate the factors of the following expression:

To factor we must find two numbers that when multiplied result in -20 and when added, result in -12.
There are no two numbers that meet this condition. Thus, the expression is not factorizable with rational numbers.
Answer:
The expression is not factorizable with rational numbers.
