The answer is $300 because you have to multiply 25x12. 10x25=250 and 2x25=50. 250+50=300.
Answer:
-35
Step-by-step explanation:
PEMDAS
Because 1/4 is a fractional number, it is also a ratio which means it is Rational. :)
Answer:
so its 50+.25(x) = y or 140. x is amount of minutes y is total
Answer:
(7,2)
Step-by-step explanation:
x + y = 9 + 2x - 3y = 8 is really two equations, and you should show this by separating x + y = 9 from 2x - 3y = 8 through the use of a comma, or the word "and," or through writing only one equation per line.
Here you have the system of linear equations
x + y = 9
2x - 3y = 8.
Let's solve this system by elimination. Mult. the 1st eqn by 3, obtaining the system
3x + 3y = 27
2x - 3y = 8
-------------------
5x = 35, so that x = 7. Subbing 7 for x in x + y = 9, we get 7 + y = 9, indicating that y = 2.
Thus, the solution to this system of equations is (7,2).
