Apedicab travels 5 miles to pick up a customer. then, the pedicab travels an average of 12 miles per hour for the entire job. which equation shows that the pedicab traveled a total of 14 miles? 5(14) + h = 12. 5 + 12h = 14 5h + 14 = 12 12(5 + h) = 14 -12 (x + 7) = 60 x = -12 x = -2 x = 2 x = 12 debbie borrows $45, and then pays $5 back each week. she currently owes $20. what will the variable stand for? her total debt how much she has paid back how many weeks have passed her account balance michael has 27 keys, which is 3 times as many as rachel. rachel has 8 more keys than ann. how many keys does ann have? ann has 1 key. ann has 17 keys. ann has 73 keys ann has 89 keys. what is the first step you would take to solve the equation 5x - 12 = -20? divide 5x and -20 by 5. add 20 to both sides. multiply 12 by 1/5 add 12 to both sides.

1.  Let h be the number of hours that Pedicab traveled.

Total distance Pedicab traveled = 14 miles.

The distance Pedicab traveled to pick up the first customer = 5 miles.

So, 5 + 12h = 14.

2.  -12(x + 7) = 60

Divide both sides by -12,

x + 7 = -5

Subtract 7 from both sides.

x = -5 - 7

x = -12

3.  Total money borrowed by Debbie = 45

Money repaid by her each week = 5

Money that she owes currently = 20

So, 45 - 5t = 20, here the variable t stands for the number of weeks passed.

4.  Number of keys Michael has = 27

= 3(Number of keys Rachel has)

So, Number of keys Rachel has = 27/3 = 9

Number of keys Rachel has = 8 + Number of keys Ann has

So, Number of keys Ann has = 9 - 8 = 1

Hence, Ann has only one key.

5.  5x - 12 = -20

To solve for x, we need to isolate it.

So, for the first step, we have to add 12 to both sides.

(2 x^3 + 7 x^2 + 5 x + 2)/(x (x + 2))

step-by-step explanation:

simplify the following:

x/x^2 + 3 x + 2 - (x (x + 1))/(x + 2)

combine powers. x/x^2 = x^(1 - 2):

x^(1 - 2) + 3 x + 2 - (x (x + 1))/(x + 2)

1 - 2 = -1:

x^(-1) + 3 x + 2 - (x (x + 1))/(x + 2)

put each term in 1/x + 3 x + 2 - (x (x + 1))/(x + 2) over the common denominator x (x + 2): 1/x + 3 x + 2 - (x (x + 1))/(x + 2) = (x + 2)/(x (x + 2)) + (3 x^2 (x + 2))/(x (x + 2)) + (2 x (x + 2))/(x (x + 2)) - (x^2 (x + 1))/(x (x + 2)):

(x + 2)/(x (x + 2)) + (3 x^2 (x + 2))/(x (x + 2)) + (2 x (x + 2))/(x (x + 2)) - (x^2 (x + 1))/(x (x + 2))

(x + 2)/(x (x + 2)) + (3 x^2 (x + 2))/(x (x + 2)) + (2 x (x + 2))/(x (x + 2)) - (x^2 (x + 1))/(x (x + 2)) = ((x + 2) + 3 x^2 (x + 2) + 2 x (x + 2) - x^2 (x + 1))/(x (x + 2)):

(2 + x + 3 x^2 (x + 2) + 2 x (x + 2) - x^2 (x + 1))/(x (x + 2))

3 x^2 (x + 2) = 3 x^3 + 6 x^2:

(2 + x + 3 x^3 + 6 x^2 + 2 x (x + 2) - x^2 (x + 1))/(x (x + 2))

2 x (x + 2) = 2 x^2 + 4 x:

(2 + x + 6 x^2 + 3 x^3 + 2 x^2 + 4 x - x^2 (x + 1))/(x (x + 2))

-x^2 (x + 1) = -x^2 - x^3:

(-x^2 - x^3 + 3 x^3 + 6 x^2 + 2 x^2 + 4 x + x + 2)/(x (x + 2))

grouping like terms, 3 x^3 - x^3 + 6 x^2 + 2 x^2 - x^2 + 4 x + x + 2 = (3 x^3 - x^3) + (6 x^2 + 2 x^2 - x^2) + (x + 4 x) + 2:

((3 x^3 - x^3) + (6 x^2 + 2 x^2 - x^2) + (x + 4 x) + 2)/(x (x + 2))

3 x^3 - x^3 = 2 x^3:

(2 x^3 + (6 x^2 + 2 x^2 - x^2) + (x + 4 x) + 2)/(x (x + 2))

6 x^2 + 2 x^2 - x^2 = 7 x^2:

(2 x^3 + 7 x^2 + (x + 4 x) + 2)/(x (x + 2))

x + 4 x = 5 x:

answer:   (2 x^3 + 7 x^2 + 5 x + 2)/(x (x + 2))

answer: 12,000
