Tyler is solving this system of equations: s 4p + 2q = 62
8p- 4 = 59
He can think of two ways to eliminate a variable and solve the system:
Multiply by 2, then subtract from the result.
Multiply by 2, then add the result to .
Do both strategies work for solving the system? Explain or show your reasoning

Muscles, a membership-only gym is hoping to open a new branch in a small city in pennsylvania that currently has no fitness centers. according to their research approximately 12,600 residents live within driving distance of the gym. muscles sends out surveys to a sample of 300 randomly selected residents in this area (all of who respond) and finds that 40 residents say they would visit a gym if one was located in their area. based on the past survey research, muscles estimates that approximately 30% of these respondents would actually join the gym if they opened one in the area. based on this information and the results of the sample survey, about how many residents should muscles expect to join its new branch? a) 134 b) 504 c) 1,680 d) 3,780

When solving this problem: 3025/5.5 = a/90.75 you get 49912.5 which would be the length of one of the sides of a square when the area is only 90.75 inches. is that answer correct, why, and how is it possible?

Common binomial factor of 6x(3x+7)+5(3x+7)
