Answer:
Rounded to the nearest hundredth:
m = 3.14
Step-by-step explanation:
0.02m + 0.04 = -0.18 + 0.09m
Isolate the m
0.02m + 0.04 = -0.18 + 0.09m
-0.09m -0.09m
-0.07m + 0.04 = -0.18
-0.04 -0.04
Now, let's simplify it.
-0.07m = -0.22
---------- ---------
-0.07 -0.07
m = 3.14 (rounded to the nearest hundredth)
divide both sides by 7 to get x alone
84/7 = 12
B.12
Answer:
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
By definition, the slopes of perpendicular lines are negative reciprocals.
Given the line:
We know that a line perpendicular to this line must have this slope:
Since that line goes through the point (8,2), we can substitute the slope 1 and these coordinates into and solve for "b":
Therefore, the equation of this line is:
Answer:
The entire race is 26.20 miles long.
Step-by-step explanation:
Given that:
Sam is 18.34 miles in the race.
This length represents the 70% of the entire length of the race.
Let,
x be the total length of the race.
70% of x = 18.34
0.7x = 18.34
Dividing both sides by 0.7
Hence,
The entire race is 26.20 miles long.
