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.

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3

its not b
