<span>6a+14=-7-a
you simplify the equation to the form, which is simple to understand
<span>6a+14=-7-a
you move all terms containing a to the left and all other terms to the right.
<span>+6a+1a=-7-14
you need to simplify left and right side of the equation.
<span>+7a=-21
you divide both sides of the equation by 7 to get a.
<span>a=-3</span></span></span></span></span>
Answer:
the answer is 1/12
Step-by-step explanation:
it is 1/12 because if there are only a pair you would have 2 dice. and since each die has numbers all the way up to 6 all you have to do is add them. and don't count all the numbers. like add 1+2+3+4+5+6. that's just plain wrong just do add the highest number on each die (6+6)
There would be 12 different digits.
The number of this always corresponds to the number in the base. Consider our current system which is base 10. We have 10 numbers we can use for digits (0-9). So a base 12 system would have to have 12.
The answer is 9y+3
simplify:
5+9y-2
=5+9y+-2
combine like terms:
= (9y)+(5+-2)
= 9y+3
For this case we have the following equation:

The variables are:
t: time in hours
d (t): distance traveled in miles.
We evaluate the distance traveled after 4 hours.
So we have that for t = 4:
Answer:
d (4) = 68
This means that after 4 hours Joanna cycled for 68 miles total
