Question

1.) A carpenter has boards of lengths 24, 36, and 42 inches that must be cut into smaller boards of equal length, with no scrap wood left over.
What is the longest length of boards he can cut?

2 inches
4 inches
12 inches
6 inches

2.) Solve -2t + 5 ≥ -7.

t ≤ -6
t ≤ 6
t ≥ -6
t ≥ 6

3.) Luis needs to run at least 150 miles in order to go with the cross country team to a summer training camp. He has forty days to pre-train for the camp.

Which inequality can be used to find how many miles Luis must run each day to meet this goal?

40 m ≥ 150
40 m ≤ 150
40 m > 150
40 m < 150

Questions four and five is the screenshots. Please help me! BRAINLEST, 5 STARS AND A THANKS!

Answer 1

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
