Answers
Explanation:
1.
Write the next three integers for the following sequences
15, 12, 9.-6, 303
1, 3, 7, 11, 15 19. 23
2. Add the following without using the number line
a) (-535) + (-609)
b) -1000 + 186
3. Find the sum of the following:
a)-638, 943, and -111
d)-87, -199 and -1347
4. Evaluate :
a) (-36) + 11 + (-73)
b)84 + (-99) + (-135)
c)(-83) + (-183) + (1833)
5. What should be added to -1984 to get the integer - 1?
6. Find the additive inverse of each of the following:
a)-138
b)1
7. Write the successor and predecessor of each of the following:
a)1001
b)-189
8. Find an integer p such that:
a) p + 11 = 0
b) p + (-3) = 0
9.Subtract the following:
a)-16 from 10
b)-11 from -119
10. Subtract the sum of -1150 and - 198 from 6234.
18. The sum of two integers is 1308. If one of the integers is -198, find the other.
11. What should be subtracted from - 2000 to get 1901?
Answer:
In general, surface tension decreases when temperature increases because cohesive forces decrease with an increase of molecular thermal activity. The influence of the surrounding environment is due to the adhesive action of liquid molecules that they have at the interface.
