0.25k + 1.5 − k − 3.5
combining like terms with rational coefficients

-  0. 75 k - 2 .

Step-by-step explanation:

Given  : 0.25k + 1.5 − k − 3.5

To find : Combining like terms with rational coefficients.

Solution : We have given 0.25k + 1.5 − k − 3.5.

On combining like term

0.25 k - k + 1.5 - 3.5.

-  0. 75 k - 2 .

Therefore, -  0. 75 k - 2 .

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
