What is expression?
An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it
A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.
Expression Definition in Math
An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:
- Constant: A constant is a fixed numerical value.
- Variable: A variable is a symbol that doesn't have a fixed value.
- Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.
- Coefficient: A coefficient is a number that is multiplied by a variable in an expression.

The pattern of the given series i.e 29,27,24,20,15,9.
Given that,
- The pattern is 29,27,24,20,15.
- Based on the above pattern we can see that the number is first decreased by 2, then 3, then 4 and so on.
Based on this, it should be like this
29-2 = 27
27 - 3 = 24
24 - 4 = 20
20 - 5 = 15
15-6 = 9
Therefore we can conclude that the pattern of the given series i.e 29,27,24,20,15,9.

weekWalk = 5(2) + 3 = 10 + 3 = 13
therefore, she walks 13 miles per week, if she walked for 29 weeks then we have:
total walked =(29)(13) = 377
so she walked 377 miles total, so her original estimate is not reasonable

Answer:
The distance Conner walks each day is 10 miles
The distance Kevin walks each day is 7 miles
The distance John walks each day is 12 miles
Step-by-step explanation:
The question is a word problem
Let the number of miles Conner walks per day = x
The given inforf the totmation in the question are;
The distance Kevin walks per day = x - 3 miles
The distance John walks per day = x + 2 miles
In three days, the difference between the total distance John walks and the total distance Kevin walks is equal to half the total distance Conner walks
The number of miles each person walks per day is found as follows;
3×(x + 2) - 3×(x - 3) = 3·x/2
3·x + 6 - 3·x - (-9) = 3·x/2
3·x + 6 - 3·x + 9 = 3·x/2
3·x - 3·x + 6 + 9 = 3·x/2
0 + 6 + 9 = 3·x/2
15 = 3·x/2
x = 15×2/3 = 10 miles
x = 10 miles
Therefore, the distance Conner walks each day = 10 miles
The distance Kevin walks per day = (x - 3) miles = (10 - 3) miles = 7 miles
The distance Kevin walks per day = 7 miles
The distance John walks per day = (x + 2) miles = (10 + 2) miles = 12 miles
The distance John walks per day = 12 miles.

Answer:
4 hours and 40 minutes
Step-by-step explanation:
speed = distance/time
distance/speed = time
