hugo went on a three-day road trip. he traveled 396 miles on the first day, 522 miles on the second day, and 324 miles on the third day. if hugo drove for 6 hours each day, what was hugo's average speed for the entire trip?
a.
87 miles per hour
b.
66 miles per hour
c.
69 miles per hour

C. 69 Miles per hour

Step-by-step explanation:

396/6=66 miles per hour

522/6=87 miles per hour

324/6=54 miles per hour

Now all we need to do is find the mean, or average.

To find the mean, add all the numbers together and divide the sum by the amount of values.

66+87+54=207

Since there are three values, divide 207 by 3.

207/3=69

The answer is C. 69 miles per hour.

Hope this helps!

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
