So for decimals, add the number of zeroes after the whole number to equal the amount of digits in the decimal value. For example, if you had 10 and 0.5 you would replace 10 with 10.0 to match the amount of digits after the decimal in 0.5
In your problem since we have four digits after the decimal, let's add a decimal and four digits after the number 15 to match it up. Now it should look like the image attached.
Once matched up you can now safely subtract.
Hope that helps!
Answer:
Greg lives 280 miles from the mountains.
Step-by-step explanation:
Given:
Time required to drive to the mountains = 8 hours.
Time required to drive home = 5 hours.
We need to find the distance Greg live from the mountains.
Solution:
Let the average rate while driving to the mountains be 'x'.
So rate while returning home =
Now we know that;
Distance is equal to Speed times Time.
So we can say that;
Distance while travelling the mountain =
Distance while returning home =
Now we know that;
Distance while travelling the mountain and Distance while returning home will both be equal.
so we get;
Combining like terms we get;
Dividing both side by 3 we get;
Substituting the value of x in any of the Distance equation we get;
Distance =
Hence Greg lives 280 miles from the mountains.
