A student was given the single matrix equation [43−84][xy]=[2035]. The student wrote the equations as 4x+8y=20 and 3x+4y=35. Use the rule about matrix equations to identify the student's mistake. What is the error in the first equation? A The coefficient with y should be −8. B The coefficient with y should be 4. C The coefficient with x should be −4. D The coefficient with x should be 8

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
