Answer:
-10 & -40
Step-by-step explanation:
the last number before you get to 0 when continuing the -30 trend is 20. 20-30= -10. Then to get the next number simply subtract 30 again to get -40. Therefore, your answers are -10 & -40.
Answer:
infinite solutions
Step-by-step explanation:
The coefficient of x in the first equation is 3 times the coefficient of x in the second equation. This means we can eliminate x by subtracting 3 times the second equation from the first:
(15x +12y) -3(5x +4y) = (18) -3(6)
0 = 0 . . . . . simplify (true for all values of x or y)
The system of equations has an infinite number of solutions.
Okay so you know the equation y=2x+80
And you know y=170 so you solve
170=2x+80
And you get y=55

Answer: 20/9
Step-by-step explanation:
Turn 4 into a fraction so 4/1
When dividing, flip the second fraction over then multiply them both, so
4/1 x 5/9
That is 4 x 5 / 1 x 9
Which is 20/9
