Nina's rate is 12.7 mph and Sophia's rate is 10 mph. Therefore, Nina is faster.
Hey there!
The main concept of pre-algebra is solving equations for variables in them.
For example, let's say you have the algebraic equation below.
x+1=3
With algebra, you need to figure what x is equal to. To do so, you will use inverse operations on both sides of the equation to isolate x one side, showing what it is equal to.
We would subtract 1 to both sides to isolate x on one side.
x+1-1=3-1
As you can see, +1-1=0, therefore, this would give us x+0, or just x. Now it is isolated and will show us what it is equal to.
x=3-1
x=2
Therefore, in our equation x+1=3, x would be equal to 2.

Answer:
- The total Minutes of the tasks involving animals.-D+F (Dog and fish)
- The total Minutes of the tasks not involving animals.-G (Garden)
- The total Minutes of the Inside tasks.-F (Fish)
- The total Minutes of the Outside tasks.-G+D (Garden and Dog)
Step-by-step explanation:
Given that:
- D = number of minutes it takes to walk his dog
- G = number of minutes it takes to water the garden; and
- F = number of minutes it takes to feed his fish
We want to match the given situations to its respective expressions:
Situation
- The total Minutes of the Inside tasks.
- The total Minutes of the Outside tasks.
- The total Minutes of the tasks involving animals.
- The total Minutes of the tasks not involving animals.
Expression
- D+F
- G+D
- G
- F
The match of the situation and respective expressions are:
- The total Minutes of the tasks involving animals.-D+F (Dog and fish)
- The total Minutes of the tasks not involving animals.-G (Garden)
- The total Minutes of the Inside tasks.-F (Fish)
- The total Minutes of the Outside tasks.-G+D (Garden and Dog)
Answer:
The solution is -5 or 11
Step-by-step explanation:
We are given the equation;
We are supposed to solve the equation;
Taking 5 to the other side;
Dividing both sides by 4
We can cube both sides;
Then we can get the fourth root on both sides of the equation;
![\sqrt[4]{ (3-x)^4} =\sqrt[4]{4096}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B%20%283-x%29%5E4%7D%20%3D%5Csqrt%5B4%5D%7B4096%7D)
We get;
Solving for x
Therefore;
Therefore, the solution is -5 or 11
Your answer is 1,027 :))))))
