Atlanta rents bikes for $12 plus $5 per hour. Calvin paid $47 to rent a bike. For how many hours did he rent the bike?

7 hours

Step-by-step explanation:

If it's $12 + $5(h) = 47, take away 12 automatically as this value doesn't depend on the hours. 47-12 is 35 so divide by 5 to get the hours. 35/5 is 7 so he rode 7 hours.

7 hours

Step-by-step explanation:

(47-12)/5

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
