Answer:

315 minutes

Step-by-step explanation:

To solve this, we must divide the gallons of the swimming pool by the rate of gallons per minute.

7,000 gallons divided by 22.2 minutes equals 315.3 minutes.

We can round this to 315.

315 minutes is how long it will take to fill the pool.

A construction manager weighs a bundle of 9 identical bricks and a 7 pound concrete block. The bundle weighs 30 pounds.

denis23 [38]

Answer:

30 = 9x + 7

Step-by-step explanation:

The total weight of the bundle = 30 pounds

The weight of the bricks = x pounds

But he carried 9 bricks = 9x pounds

He also carried additional 7 pounds of concrete block.

An equation to show the total weight he carried is

30 pounds = (9x + 7) pounds

Since 9x represents the total weight of the bricks he carried

7 represents the weight of the concrete block

And 30 pounds represents the total weight of everything he carried.
