Answer:

The answer to your question is 60.7 km

Step-by-step explanation:

This is a ratio and proportion problem, so let's write the proportion.

                                  3  :  26  : :  7  :  x

1.- Convert the expression to a fractional form.

                                  \frac{3}{26} = \frac{7}{x}

2.- Solve the proportion, cross multiplying and back off.

                                 x = \frac{26 x 7}{3}

                                 x = \frac{182}{3}

                                 x = 60.7 km

I would say yes and no because estimations aren't exact, they're close to the correct value. Trent's estimation is correct since 53+12=65, if we were looking for the exact distance, Trent would be wrong because there are fractions too, so the exact value would be 66 (5/12) or 65 (17/12).

Hope this helped :)

mash [69]

Answer:

4.6

Step-by-step explanation:

Hello!

To find the average we add all the numbers together and divide by how many numbers we added

6.8 + 5.6 + 3.4 + 2.5 + 4.7 = 23

We added 5 numbers so divide the total by 5

23/5 = 4.6

The answer is 4.6

Hope this helps!
