Answer: A. x= 0.25

Step-by-step explanation:

To find the area of a rectangle ,we need to multiply the length by the width.

It says the length is 3.2 and with is x so 3.2 times x has to equal 0.8 which is the area.

3.2 * x = 0.8 Now solve for x.

3.2x = 0.8 Divide both sides by 3.2

x= 0.25

An animal shelter is building new cages for 26 dogs and 34 cats. All the animals are kept separate. The first crew can build a c

Oliga [24]

The animal shelter is building cages for 26 dogs and 34 cats.

26 + 34 = 60

It needs to build 60 cages.

The first crew builds 1 cage in 1 hour. Rate: 1 cage/hour

The second crew builds 1 cage in 2 hours, or 1/2 cage in 1 hour. Rate: 1/2 cage/hour

They work together for x hours and build all 60 cages.

In x hours, the first crew builds 1 cage/hour * x hours = x cages.

In x hours, the second crew builds 1/2 cage/hour * x hours = 1/2 x cages.

Combined, they build 60 cages.

x + 1/2 x = 60

x + 0.5x = 60

1.5x = 60

x = 40

Answer: It will take 40 hours.

Check: In 40 hours, the first crew builds 40 cages.

In 40 hours, the second crew builds 20 cages.

40 + 20 = 60

In 40 hours, the two crews build 60 cages.

Our answer above is correct.
