Answer:

  4 hours 55 minutes

Step-by-step explanation:

Time, speed, and distance are related by ...

  t = d/s

  t = (177 mi)/(36 mi/h) = 4 33/36 h = 4 11/12 h

The fractional part of this time is ...

  11/12 hour is (11/12)(60) = 55 minutes

The van will take 4 hours and 55 minutes to travel a distance of 177 miles.

aev [14]

Answer:

The expression that is equivalent to the given expression is:

              5x+60

Step-by-step explanation:

It is given that:

if you add 12 marshmallows to each of 5 bags of marshmallows, and each bag started with the same number of marshmallows.

so, let x be the initial number of marshmallows in each bag and now 12 are added to each bag this means that the number of marshmallows in each bag is:

                  x+12

Hence, total number of marshmallows in 5 bags is:

      5(x+12)=5×x+5×12

     5(x+12)=5x+60

        Hence, the answer is:

                    5x+60

Given that ABCD is congruent to EFGH, therefore:

CD ≅ GH

Since CD = 40 ft, therefore, GH will be 40 ft.
