A) For a food truck event, you sold 750 chicken tacos and 520 beef tacos. Write an expression for the total cost of both tacos if x = cost for a chicken taco and y = cost for a beef taco.

B) Given each chicken taco is $3 and each beef taco is $2.50, determine the total cost of both tacos sold at your food truck event. Show your work.

Pls do b if do I will give you 100 points

Need ! give step by step solutions on how to solve number one \frac{9-2\sqrt{3} }{12+\sqrt{3} } number two x+4=\sqrt{13x-20} number three (domain and range) f(x)=2\sqrt[3]{x} +1

What is an equivalent expression to ( 14400^4 )^8

The life (in hours) of a magnetic resonance imagining machine (mri) is modeled by a weibull distribution with parameters β = 2 and δ = 370 hours. (a) determine the mean life of the mri. (round your answer to 2 decimal ) determine the variance of the life of the mri. (round your answer to 1 decimal ) what is the probability that the mri fails before 250 hours? (round your answer to 4 decimal places.)
