Answer:
480 miles
Equation:
Step-by-step explanation:
#First we calculate the average time it takes to walk one mile:
#We then calculate the number of miles he walks in 8 weeks.
-Given he walks one mile per day, 4 times a week;
#Multiply the distance traveled by the average time per mile to get total time spent:
Hence, the walking time over the 8 period will be 480 minutes
#This can be represent as:
Let w be the number of weeks and t be the time in minutes.
The time spent on walking per week is 
Therefore the time spent walking in w weeks is represented as:
Answer:
1) -6
2) x = -y +7 if you set all terms equal to zero.
Step-by-step explanation:
1) Isolate x by dividing -42 by 7. x = -6
2) Set the entire expression equal to zero.
x + y -7 = 0
Isolate x on one side of the equation. Remember to change signs when moving terms across the equal sign.
x = -y +7 if the original expression is set equal to zero.
Answer:
25
Step-by-step explanation:
Move 125^4/3 to the numerator using the negative exponent rule 1/b^n=b^-n.
125^2 x 125^4/3
Simplify the expression.
5^3(2/3)
Cancel the common factor of 3.
5^2
Raise 5 to the power of 2.
25
Expand the left and the right side .
then you simplify
then continue ...
you will get x = -2
Answer: 84 tickets
Step-by-step explanation:
We are told the ratio of the number of tickets Mark collected to the number of tickets Julia collected is 4:3
(1)
In addition, we are told Julia collected 36 tickets:
(2)
Substituting (2) in (1):
(3)
Isolating 
:
(4)
Adding Mark's tickets to Julia's:
Therefore, both collected 84 tickets.
