Can you guys help me with integers it these four problems for the first image do 18 and 19 for the second it’s 7 and 11 please help I need it before 6:00 pm please look up the answers if you have to whoever answers these questions correctly I will mark brainliest.

18. 20,000.

19. 0

7. 1

11. 101

Step-by-step explanation:

18. I think is stays the same, because an integer is a number that is not a fraction. So still 20,000.

19. Sea level is at zero altitude. So answer is 0.

7. |17-16| = |1| = 1. The lines around it are called absolute value signs and mean to make the answer positive.

11. |-101| = 101. As said before the lines mean to make the inside part positive.

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
