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.

3.5 m

Answer:

This question seems to be incomplete, I guess that we have a circular pool, with a diameter of 3.5 m.

Now, the circunference of a circle can be written as:

C = 2*pi*r

where:

pi = 3.14

r = radius = half of the diameter = 3.5m/2 = 1.75m

Then replacing those values in the equation for the circumference we have:

C = 2*3.14*1.75m = 10.99 m.

And knowing that the value of pi is actually larger than 3.14 (pi = 3.1415926535....)

We can safely round up the circumference to the next whole number, C = 11m

marysya [2.9K]

Answer: 20


Step-by-step explanation:

Follow order of operations (PEMDAS)

20÷1÷[(10÷5)÷2]     Given

20÷1÷[(2)÷2]            Do 10÷5 in parenthesis

20÷1÷[(1)]                 Do (2)÷2

20÷1                        Do 1÷[(1)]

20                           Do 20÷1, and that is your answer
