Answer:
- first mechanic: $105/hour
- second mechanic: $55/hour
Step-by-step explanation:
Let r represent the rate charged by the first mechanic. Then 160-r is the rate charged by the second mechanic. The total of charges is ...
20r +5(160-r) = 2375
15r +800 = 2375 . . . . . . eliminate parentheses
15r = 1575 . . . . . . . . . . . . subtract 800
r = 105 . . . . . . . . . . . . . . . divide by 15. First mechanic's rate.
160-r = 55 . . . . . Second mechanic's rate
The first mechanic charged $105 per hour; the second, $55 per hour.
Answer:
k = -6.29
Step-by-step explanation:
91 - 2 + 7k + 1 = 46
add all like terms
90 + 7k =46
subtract
90 + 7k = 46
-90 -90
------------------------
7k = -44
divide
= 
(these arent fractions thats just how i divide things :))
= -6.28571428571
round to nearest hundredth
k= -6.29
goes up to 9 because 5 makes 8 go up one when rounding
sorry for asking so many questions. hope this helps
