Ed is on a road trip. he has already traveled 220 miles and is driving at a rate of 61 miles per hour. which equation could be used to find how many hours, x, ed has left in his road trip if he is traveling 677 total miles? a. 61x + 677 = 220 b. 220x + 61 = 677 c. 61x + 220 = 677 d. 220x + 677 = 61

C

Step-by-step explanation:

Imagine your going 61 steps per hour and you have already walked 220 steps. You want to walk 677 steps in total. First you minus the amount you have done then each hour add 61 steps which would be the x for each hour

Question: Ed is on a road trip. He has already traveled 220 miles and is driving at a rate of 61 miles per hour. Which equation could be used to find how many hours, x, Ed has left in his road trip if he is traveling 677 total miles?

 61x + 220 = 677

Explanation:  you minus the amount you have done then each hour add 61 steps which would be the x for each hour

according to egenuity the answer is

step-by-step explanation:

d. 344.22

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
