Answer:

1) 12

2) t ≤ 6

3) 40 m ≥ 150

4) The second option

5) -1 < x

Step-by-step explanation:

1) Since he wants to seperrate the boards equally, you just have to find a common mulitple of all the boards that equate to the same number

2) First subtract 5 from both sides, (-2t ≥ -12), and then divide both sides by -2, when you divide both sides by a negative number in an equality, you always swith the sign so the answer is t ≤ 6.

3) I think its supposed to be at least 4 miles a day or more, but 40 miles a day or more each day is good enough

4) You can automaticly delete the first and last options and it's the second option because it shows that 'n' is a number that is bigger than the number -3

5) You can eliminate anything that has equal to line under the sign, and it's -1 < x because the line graph shows that something (x) is greater than -1
