Atrucking company makes 50 deliveries in 5 days how long will it take for them to deliver 400

This is the application of ratio and proportion. You have to formulate the proportion for this problem:

50 deliveries : 5 days = 400 deliveries : x days

The inner numbers when multiplies should equal the product of the outer numbers.

400 (5) = 50x

50x = 2,000

x = 40

Therefore, it would take 40 days for the trucking company to deliver 400 deliveries.

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
