c
Answer:
D.abc,cab
Step-by-step explanation:
We are given that some pairs of terms
We have to find the pairs of terms is composed of like terms.
Like terms : In algebra , like terms are those terms in which variables with power are same in the terms.
A.4mn,3my
In given pair ,variables n and y are not same .Therefore, 4 mn and 3 my are not like terms.
B. 2a , 2b
In given pair variable a in first term and variable b in second term are not same. Therefore, given pair are not like terms.
C.-3x,3y
Variable x and y are not same therefore, it is not the pair of like terms.
D.abc, cab
In given pair variable a with power is same in both terms, variable b with power is same in both terms and variable c with power is same in both terms.Hence, the pair is a pair of like terms.
Answer: D.abc cab.
Answer: If the solution's boiling point drops because salt is added to the soltuiton, then the reason the solution boils sooner is the addition of salt to the solution
Step-by-step explanation:
The re are two cause - consequence relations inside an other one.
I use 3 different cause - consequence connectors not to mix them up.
A --> D equals “ D because A “
A --> S equals “ the reason S happens is A “
(A --> D) --> (A --> S) Equals “ if (A --> D) then (A --> S) “
Answer:

Step-by-step explanation:
The general formula for the twelfth term of a geometric sequence is:

Where
is the first term and r is the common ratio
In this case we know that:

The equation is:

So for
we look for 



So you need to get C by itself. So you are going to divide -1/7 by 21. Then that will give you the answer x=3
