Answer:I think 11
Step-by-step explanation: 11 because one can do no more than 11 packages so the most potential one most be 11 since it can't do 18 but the 18 can do 11 and the max of the other one is 11
Answer:
Hence, a carpenter can paint a maximum of 7 chairs.
Hence, option A is correct.
Step-by-step explanation:
A carpenter has less than 120 min. to spend painting furniture each day.
Today, he has spent 30.5 min. painting a desk.
Now he will paint x chairs, each of which takes 12.5 min.
i.e. he will take a total of 12.5x minutes in painting 'x' chairs.
Also total time spent on painting furniture each day will be equal to time spent on painting a desk and all of the chairs.
Hence,
30.5+12.5x<120 (since the total time he spends on painting is less than 120 mins.)
⇒ 12.5 x<120-30.5
⇒ 12.5 x<89.5
⇒ x<7.16 ( on dividing both side of the inequality with 12.5)
Hence, a carpenter can paint a maximum of 7 chairs.
Answer:
-7 is -7 units away from zero. Its opposite is 7 from zero.
Step-by-step explanation: Count from 0 how many digits away it is
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.
