Answer:
The social studies teacher should draw a random sample from all the students in each grade.
Step-by-step explanation:
The teachers will not be doing the activity, so their opinion is irrelevant. All boys in each grade targets a some audience and leaves the girl's voices unheard. All the students in the social studies club only represent a small portion of students who take the class. A poll of all the students in each grade will give the teacher the results they desire.
(Also, the formatting of this question is absolutely <em>horrible.</em> I had to reread it several times to understand the question. If you want people to answer you, make it legible.)

Step-by-step explanation:
(1)
p + q
= 2i - j + i + j ← collect like terms
= 3i
(2)
p - q
= 2i - j - (i + j) ← distribute parenthesis by - 1
= 2i - j - i - j ← collect like terms
= i - 2j
(3)
2p - 3q
= 2(2i - j) - 3(i + j) ← distribute parenthesis
= 4i - 2j - 3i - 3j ← collect like terms
= i - 5j
Answer:
no
Step-by-step explanation:
The starting number is 245.So it’s already pretty deep in the water,then it goes down 83 feet MORE.so that’s 245+83=328 feet. Then the submarine goes UP 103 feet from that point,so 328-103=225 feet,so its closer to the surface than at the beginning(245ft)
