For the answer to the question above, If you've noticed, the statement mentioned "a number". Let's assign x to be the number. The first statement is twice a number (2x). Then, decreased by the quotient of that number and 2 (-x/2). Lastly, the statement at least 12 is written as >12.
So the answer is
2x - (x/2) >12
C , a relationship between two variables can be expressed by an equation in which one variable is equal to a constant.
The slope is rise over run so it would be -1/3
Answer:
a = 3.2
Step-by-step explanation:
2( -a - 8) + 7a = 0
-2a -16 + 7a = 0
5a - 16 = 0
5a = 16
a = 16/5
a = 3.2
