Answer:
c=1146
Explanation:
Given 5y=3478 - 3c
Then if y= 8 then substitute y in the equation as
5*8=3478-3c
40=3478-3c ------collect like terms as;
3c=3478-40
3c=3438
c=3438/3 =1146
The energy associated with food is chemical energy.
The food contain carbohydrates, proteins, vitamins and minerals, that are used by chemical reactions in the live organisms (the metabolism) to build the cells that form our tissues (muscles, bones, blood).
The chemical energy is stored as chemical bonds in the cells and is released when the bonds break giving energy that we use to run about, and move and talk (kinetic and sound energy).
