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.
Answer:
b or c
Step-by-step explanation:
Answer:
The temperature with the highest frequency is 54
Step-by-step explanation:
Given
The above data
Required
The temperature with the highest frequency
The first step, is to plot the stem and leaf plot.

Next, is to identify the leaf with the highest frequency.
The leaf is 4 (with frequency 2)
Next, is to identify the accompanying stem of the leaf
The stem is 5
<em>Hence, the temperature with the highest frequency is 54</em>
Answer:
The answer would be 3
Step-by-step explanation:
This is because, hope this makes sense, Shes 8 years older and the answer choices were: 3, 4, 11 and 12, well 3+8=11 and it says next year she will be 3 times his age, still being 8 years older, next year lance will be 4 and whats 3 years times 4, twelve. And whats 8 years older than four 12. Hope this makes sense but it has to be 3.
Answer:
D = 12.94 m
Step-by-step explanation:
Coordinates of first tree = A(0,8)
Coordinates of second tree = A(12,4)
We need to find the distance between the two trees. We can find it using distance formula for coordinates as follows :

We have, x₁ = 0, x₂ = 12, y₁ = 8, y₂ = 4
Now using distance formula,

So, the distance between the two trees is 12.64 m.
