Answer:
associative! property! of! addition!
Step-by-step explanation:
we change the order of the addends but the sum doesn't change
Answer:
92.8 km
Step-by-step explanation:
s=d/t
58=d/1.6
58*1.6=d
92.8=d
Answer:
Option 1
Step-by-step explanation:
option 1=243
option 2=125
We know that
<span>1½ cup of cleaner-------> (1*2+1)/2-----> 3/2 cup of cleaner
</span><span>the ratio of cleaner to water=(3/2)/12---> 3/(2*12)--> 3/24--> 1/8
the answer is
1/8</span>
If
is odd, then
while if
is even, then the sum would be
The latter case is easier to solve:
which means
.
In the odd case, instead of considering the above equation we can consider the partial sums. If
is odd, then the sum of the even integers between 1 and
would be
Now consider the partial sum up to the second-to-last term,
Subtracting this from the previous partial sum, we have
We're given that the sums must add to
, which means
But taking the differences now yields
and there is only one
for which
; namely,
. However, the sum of the even integers between 1 and 5 is
, whereas
. So there are no solutions to this over the odd integers.
