6x-6
Step-by-step explanation:
add both equations together, then multiply that by 2
2*(2x+3+x-6)
if you walk 4 miles in 1 hour that would be 1 mile every quarter of an hour
a quarter of an hour is 15 minutes
so it would take 15 minutes to walk 1 mile
4 + 2 + 7 = 13
7/12 + 3/4 + 5/12 = 7/12 + 9/12 + 5/12 = 21/12 = 1 9/12 = 1 3/4
13 + 1 3/4 =
14 3/4 <===
10.44!
Hope this helped :)
Answer:
Any number by ten is the number and add how many 0's there are in an equation at the end. If you are doing it with decimals you would move one space to the right or left depending if it i negative or positive.
Step-by-step explanation:
If you times a number by ten and go the long way it will still equal up to the same number if you just add the amount of zero's it has in the equation to the end. Example's: 10x10=100 & 11x10=110.
