Is this rearranging formulae? Because, if so-
m=4 (2t+w)
5
m(2t+w)=4
5
4 divide m= 2t+w
5
(4 divide m) - w all over 2
(5
Answer:
Yamal can move the ice to 82 km in approximately <u>15 hrs</u>.
Step-by-step explanation:
Given:
Speed = 5.5 km/hr
Distance = 82 km
Let time be represented as 'x'.
We need to find the number of hours required to travel 82 km.
We know that Distance can be calculated by the product of Speed and time.
Framing above sentence in equation form we get;
Distance = Speed × Time
Substituting the given value we get;

Hence The expression for number of hours is 
Solving the equation to find the value of x we get;

Hence Yamal can move the ice to 82 km in approximately <u>15 hrs</u>.
7 - 3 2/5 =
7 - 17/5 =
35/5 - 17/5 = 18/5 = 3.6
I found your complete question in another source.
See attached image.
For this case what you should see is that you have two similar triangles.
We then have the following relationship:
((AB) / (BX)) = ((CD) / (DX))
We cleared CD:
CD = ((AB) / (BX)) * (DX)
Substituting the values:
CD = ((12) / (5)) * (2.5)
CD = 6
Answer:
CD = 6
