Solve the system of linear equations. (enter your answers as a comma-separated list. if there is no solution, enter no solution. if the system has an infinite number of solutions, set x3 = t and solve for x1 and x2 in terms of t.) 5x1 − 4x2 + 6x3 = 2 x1 + x2 − 3x3 = 5 4x1 − 5x2 + 9x3 = 6 (x1, x2, x3)

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

the height of the surface increases from the center out to the sides of the road

it is c!
