Answer:
30 minutes
Step-by-step explanation:
Walk rate = 88 paces/ minute
Average length of pace = 0.875 m
Time taken to walk 2.31 km ;
The distance in metres :
1000 m = 1 km
2.31 km = (1000 * 2.31) = 2310 m
Recall :
Time taken = distance / speed
Distance walked in a minute = 88 * 0.875 = 77 m
Time taken = 2310 / 77
Time taken = 30 minutes
Answer
Example 1 Solve for x and check: x + 5 = 3
Solution
Using the same procedures learned in chapter 2, we subtract 5 from each side of the equation obtaining
Example 2 Solve for x and check: - 3x = 12
Solution
Dividing each side by -3, we obtain

Answer:
x=149
Step-by-step explanation:
pythagoras theorem dictates that a squared +b squared= c squared
in this case, c=x
51*51+140*140=x*x
2601+19600=x*x
22201=x*x
x=149
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
5x - y = 8 ( subtract 5x from both sides )
- y = - 5x + 8 ( multiply through by - 1 )
y = 5x - 8 ← in slope- intercept form
with slope m = 5 and y- intercept c = - 8
