Answer:

Step-by-step explanation:
step 1
Find the units rate of the first glacier

using proportion

step 2
Find the units rate of the second glacier

using proportion

step 3
Find the difference

The answer is 4:4 it takes 4 of each
The answer is B.
Parallel lines as they are in the same plane but never meet.
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.
Answer:
The answer would be c
Step-by-step explanation:
i choosed c because u have da negative sign in front of 4 and 2 and positive numbers with 1 and 2
