Answer:
1400
Step-by-step explanation:
67 rounds to 70 because 7 is bigger than 5 so it rounds up. 23 rounds down since 3 is smaller than 5.
So, 70x20=1400
15 - (4m - 5) + 32
=15 - 4m + 5 + 32
=- 4m + 52
x < -2.5 and x > 1
The answer is C
2.640 and 10,560
264 * 410 = (264 * 400) + (264 * 10) = 105,600 + 2640 = 2.640 and 10,560
56 multiplied by 9 = 504
55.8 rounded is 56, and 9.12 rounded is 9
