james went out for a long walk . He walked 3 2/5 of the mile. then he sat down to take rest . After that he walked 5/7 of a mile
kotykmax [81]

Answer:

Altogether James walked 4\frac{4}{35} miles.

Step-by-step explanation:

The question involves mixed fractions. Mixed fractions are first converted into proper fractions and then any operation can be performed on them.

Given

Distance of first walk = 3\frac{2}{5} of a mile

Distance of second walk = 5/7

In order to find how much he walked altogether, we have to find the sum of both fractions.

Total\ distance = 3\frac{2}{5}+\frac{5}{7}\\= \frac{17}{5}+\frac{5}{7}\\=\frac{17*7}{5*7} + \frac{5*5}{7*5}\\=\frac{119}{35} + \frac{25}{35}\\=\frac{119+25}{35}\\=\frac{144}{35}\\=4\frac{4}{35}

Hence,

Altogether James walked 4\frac{4}{35} miles.

If 3d – (9 – 2d) = 51, find the value of 3d.
Vanyuwa [196]
First you open up the brackets so the sign for 2d changes to positive. So it will look like 3d-9+2d=51 then u simply the 3d-9+2d that should give 5d-9=51. Then you add 9 to both sides of the expression 5d-9+9=51+9. That will be 5d =60 so you divide 5 on both sides to find the value of 1 d which is 60/5=12 then to find 3d you multiply the value of d by three so it's 12(3)=36
