Acar will be traveling a total distance of 520 miles. the first part of the trip takes 2 hours, and the car’s average rate is 65 miles per hour. if the entire trip takes 8 hours, what is the car’s average rate, in miles per hour, during the second part of the trip? 49 57 50 65

  65

Step-by-step explanation:

65 mph x 2 = 130 miles in 2 hours

520 total miles - 130 = 390

8 total hours - 2 hours = 6 hours

390 / 6 = 65 ave mph

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
