Answer:

Step-by-step explanation:
<em>add 8 to both sides</em>

<em>divide both sides by 9</em>

Answer:
Speed = 0.0003miles/hr
Step-by-step explanation:
Speed of object = 1 mile/hour
For every meter it travels, its acceleration increases by 1 mile/hour
∆Distance = increase in distance
∆speed = 1 meter
The speed and the distance are constant
Speed = distance/time
Time = distance/speed = 1meter/(1 miles/hr)
Convert meter to miles
1609.34 meters = 1mile
1meter = (1meter × 1mile)/(1609.34 meters)
1 meter = (1/1609.34)miles
Time = distance/speed = (1/1609.34)miles/(1 miles/hr)
Time = (1/1609.34)hr
We are to determine the speed the object would be travelling in half of an hour?
In 1hr, it travels (1/1609.34)miles
In ½hr, it travels = (1/1609.34)(½)hr
Speed = 0.0003miles/hr
It will be travelling 0.0003miles/hr in half of an hour
Answer:
-k-h/r-s
When solving the goal is to get x on one side and not x on the other.
rx + h = sx - k
rx - sx + h = -k <------- subtract sx from both sides
rx - sx = -k - h <-------subtract h from both sides
x (r - s) = -k -h <------factor out x which is in both rx and sx
x = - k - h / r - s <-------divide by r-s on both sides
The sales tax would be $1.36 so the total cost would be $35.36
