the coefficient is any real number so in 67xy the coefficient would be 67
Answer:
4/15 pages per minute
Step-by-step explanation:
10 2/3=32/3
(32/3)/40
(32/3)(1/40)=32/120
simplify
4/15
18a+9 is the equivalent expression.
Answer:
d = w + 3 (first equation)
2d = 2w + 3 (second equation).
The second equation is equivalent to the first one.
In other words, two equations carry the same information as the first one, not more.
In the language of linear algebra, the system is dependent
