Hudson went into a restaurant and bought 8 hamburgers, and a drink for himself. The total cost was $51.50 Pedro went into the same restaurant and bought 4 hamburgers and a drink for himself. The total cost
was $39.30
Let x represent the cost of a hamburger and y represent the cost of a drink

The equation that represents Hudson’s purchase is x + 8y = 51.50

The equation that represents Pedro’s purchase is 4x + y = 39.50

I need the answer for both, thanks

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
