Let the distance to his office be x, then
On monday, speed = x/20 miles per minutes = 3x miles per hour
On tuesday, speed = (3x + 15) miles per hour
Time = distance / speed
(20 - 6)/60 hours = x/(3x + 15) hours
7/30 = x/(3x + 15)
7(3x + 15) = 30x
21x + 105 = 30x
30x - 21x = 105
9x = 105
x = 105/9 = 11.7 miles
Therfore he travels an average of 11.7 miles to work.
Answer:
After 4 more days
Step-by-step explanation:
The remaining amount of money needed to reach the goal is $200 this is because 1000-800=200
Now we divide the 200 by the amount Karen earns a day
200/50=4
That means after 4 more days Karen will have $1000
You forgot to post the function
Answer: For -6+14<-28, the answer is....
Inequality form : x>7
For 9x+15<-=12, the answer is...
Inequality form : x <= -3
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable. (THIS IS FOR BOTH ANSWERS!!)
Hope this helps you out.
