In a paint factory, an old conveyer line has filled 20 barrels of paint, and is filling more at a rate of 7 barrels per minute.
vagabundo [1.1K]

It takes 10 minutes for the two lines to have filled an equal number of barrels

Each line will have filled 90 barrels

<em><u>Solution:</u></em>

Let "x" be the number of minutes

<em><u>The old conveyer line has filled 20 barrels of paint, and is filling more at a rate of 7 barrels per minute</u></em>

Thus, a equation is framed as follows:

Old conveyor: 20 + 7(number of minutes)

Old conveyor: 20 + 7x ------- eqn 1

<em><u>A worker just switched on a newer line that can fill 9 barrels per minute</u></em>

Thus, a equation is framed as follows:

New conveyor: 9(number of minutes)

New conveyor: 9x -------- eqn 2

<em><u>In a little while, the two lines will have filled an equal number of barrels.</u></em>

<em><u>Thus, eqn 1 must be equal to eqn 2</u></em>

20 + 7x =9x\\\\9x - 7x = 20\\\\2x = 20\\\\x = 10

Thus it takes 10 minutes for the two lines to have filled an equal number of barrels

<em><u>How many barrels will each line have filled? </u></em>

Substitute x = 10 in any one of equations

Substitute in eqn 2

9x = 9(10) = 90

Thus each line will have filled 90 barrels

a bicyclist covered 5/7 of his route and an additional 40 miles. he has yet to cover 118 miles less than 0.75 of his route. how
Oduvanchick [21]

The length of the route of a bicylist that has covered 5/7 of his route and an additional 40 miles and yet to cover 118 miles less than 0.75 of his route is 168 miles.

<h3>How to form equation and solve for the variable?</h3>

The bicyclist covered 5 / 7 of his route and an addditional 40 miles.

Let

x = distance of his route in miles

Hence,

distance covered = 5 / 7 x + 40

He has yet to cover 118 miles less than 0.75 of his route. Therefore,

distance not covered = 0.75x - 118

Distance of his route = 5 / 7 x + 40 + 0.75x - 118

x = 5 / 7 x + 40 + 0.75x - 118

x = 1.464x - 78

x -  1.464x = -78

-0.464x = -78

x = 78 / 0.464

x = 168.103448276

x = 168 miles

Sample response: <span>Yes, the fan will provide enough airflow. The volume of the ranger station is 720 cubic feet. The ranger station requires a 720 CFM fan. 1,500 CFM is greater than 720 CFM, so it will be enough airflow.</span>
