Answer:
x = 4
Step-by-step explanation:
DO + OB = DB
15 + 3x + 7 = 9x - 2
3x + 22 = 9x - 2
3x + 24 = 9x
24 = 6x
4 = x
The sum of y+x, or 5+7, is rational. This is because each integer(non fraction/decimal)is rational, it is also rational.
The team has lost only 6 games (according to the comments). Let's say "x" is the amount of losses and "y" is the amount of wins.
For every loss, they have 3 wins, so in the end, this would be the equation:

or

Although the first one would be the easier and most understandable to read.
So:
y = 3(6)
would equal
18
Answer:
6 mins
Step-by-step explanation:
An ant can crawl 3/4 of a yard in 1/2 minute. How long will it take for the ant to crawl 12 yards?
Ant crawls 3/4 of a yard in = 1/2 min = 60/2 sec = 30 sec
Ant crawls 12 yards in = 12 * 30 = 360 sec = 360/60 = 6 minutes
A linear system can have infinite solutions if both systems represent the same line. if a linear system down not represent the same line then it can only have one or no solutions. No solution is if the system is representing parallel lines and one solution represents an intersection of the two lines. in a nonlinear system you can have infinite or up to a maximum of intersections as the highest degree of the systems.
