Answer:
The answer to your question is C. 3.2
Step-by-step explanation:
| 3.2 |
lines | | mean absolute value, and absolute value means the distance of a number to the origin (0,0) it does not matter the sign.
Then to answer your question just do not write the | | and consider it as a positive sign.
If your question had a negative number ex. | -3.2 | the answer would also be 3.2.

Answer:
520 loaves
Step-by-step explanation:
First, let's find how many white loaves he baked.
Let's make a proportion.
white loaves/brown loaves= white loaves/brown loaves
He baked 3 white loaves for every 2 brown loaves. He baked x white loaves for 208 brown loaves.
3/2=x/208
Now, we have to solve for x. To do this, we have to get x by itself. x is being divided by 208. To reverse this, multiply both sides by 208
208*3/2=x/208*208
208*3/2=x
312=x
He baked 312 white loaves.
Now, we have to find the total number of loaves he baked.
To do this, add the brown loaves and the white loaves.
brown loaves+white loaves
He baked 208 brown loaves and 312 white loaves
208+312
520
He baked 520 loaves in total
Answer:
1.98 × 10^10
Step-by-step explanation:
First solve for how many text messages were sent out per one month:
22,000,000 × 900
19,800,000,000
Convert into scientific notation:
1.98 × 10^10
In scientific notation, there can only be one number before the decimal. The rest of the numbers must be after the decimal; hence, why I put the numbers 9 and 8 after the decimal. If the rest of the numbers are zeros, you do not have to add them after the decimal. Instead, starting from right to left, count the number places until you reach your decimal. The number you have counted will be your exponent. I counted nine 0's, one 8, and one 9 which made this exponent 10 as there were 10 decimal placements.
