Answer:
1. Re-writing an equation to remove all the variables.
Step-by-step explanation:
Backtracking is the procedure required for solving problems that has series of parts combined as one. It involves the retracing each part after one or two parts has been solved to solve the whole problem.
In mathematics when given an equation with variables, the solution can be obtained by calculating the values of each variable. To determine the final solution sometimes requires substitution procedure.
The best option that describe backtracking in maths-sense is; re-writing an equation to remove all the variables.
Volume = pi * r^2 * h
h = 3r
pi * r^2 * (3r) = 24 pi
3r^3 = 24
r^3 = 8
r = 2
Height = 3*2 = 6 units
distribute the -3 to the -4y and the 3 making the question 12y-9+7y then add common factors to get 19y-9
The answer choice is C, because the problem is asking for the outcome of either one of the answers. Then you just add them together and the answer is 0.5+0.3=0.8. Hope this helped!
