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.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
