Answer:
14
Step-by-step explanation:
When looking at a sequence, look at the difference between each number. If you look at the first 4 numbers, you will observe:
-6 + 5 = -1
-1 + 5 = 4
4 + 5 = 9
Therefore, the next number must be 9 + 5 = 14.
Answer:
2
Step-by-step explanation:
either the four friends give you the money first then you give it to the three friends That is one Or youcan ask your parental figure to own you three dallors then you will have more money at the End.
Simultaneous Equations
3x + y = 4
5x - y = 22
The signs of the matching values aren't the same so we add the rest of the equations.
8x = 26
Divide both sides by 8 to get x = 3.25
Now substitute back into the first equation.
(3 x 3.25) + y = 4
9.75 + y = 4
Subtract 9.75 from both sides
y = -5.75
