Answer:
170.3 miles per hour
Step-by-step explanation:
Javon won Indianapolis 500 race in 2011 with an average speed of 170.265 miles per hour. What was his average speed to the nearest tenth of a mile per hour?
From the above question, we are asked to approximate to the nearest tenth of a mile.
The number that falls under the tenth of a mile, is the number that is immediately after the decimal.
Hence, for:
170.265 miles per hour:
2 is the number in the tenth place, the number after 2 is 6, it is a number that is higher than 5. So we add 1 to 2
Therefore,
170.265 miles per hour to the nearest tenth of a mile = 170.3 miles per hour.

Answer:the number of BlackBerry that Arlene had initially was 276
Step-by-step explanation:
Let x represent the number of BlackBerry that Arlene had initially.
She gave 216 to her teachers. This means that she is left with x - 216
Then she dropped 12. This means that she would be left with x - 216 - 12 = x - 228
Later, she ate 18. This means that she would be left with x - 228 - 18 = x - 246
Finally, she gave half of what she had to her friend. This means that the amount that she gave to her friend is (x - 246)/2 and the amount that she has left would be
(x - 246)/2
Now, she has 15. This means that
(x - 246)/2 = 15
x - 246 = 2 × 15 = 30
x = 30 + 246 = 276

<h2>3x - 10</h2>
Step-by-step explanation:
(5x - 3) - (2x + 7).
<u>Remove the brackets</u>
That's
5x - 3 - 2x - 7
<u>Group like terms and simplify</u>
That's
5x - 2x - 3 - 7
We have the final answer as
<h3>3x - 10</h3>
