The Martinez Family has driven 240 miles so far. Their total trip is 300 miles. What percentage of the trip have they already driven?
Answers
Answer:
80%
Step-by-step explanation:
Percentage of the trip covered = [tex]\frac{miles driven }{total miles}[/tex] × 100
I am multiplying by 100 because to convert to percentage, we have to multiply by 100
Miles drive = 240
Total miles = 300
[tex]\frac{240}{300}[/tex] × 100 = 80%

Find the solution to the equation.
n + 13 = 52
Answers
Answer:
N = 39
Step-by-step explanation:
N + 13 = 52
-13. -13
N = 39
Answer:
n = 39
Step-by-step explanation:
To find what n equals, I want to get it alone on one side of the equation.
To do this, I move 13 to the right side of the equation by subtracting 13 from both sides.
13-13=0 so n is the only value on the left side
52-13=39.
You are now left with n = 39
To check that this is right, add 13 to 39. It equals 52, so you know the answer you found is correct.

What is the slope of the line that passes through M(-6, 1) and N(2, 5)?
Answers
Answer:
m = 1/2
Step-by-step explanation:
As we move from M to N, the x-coordinate increases from -6 to 2, a jump ('run') of 8 units. Likewise, the y-coordinate increases from 1 to 5, a jump of 4 units. The slope of the line passing through these two points is thus
m = rise / run = 4/8 = 1/2
