what about using 20-30-40-5
Step-by-step explanation:
the sequence is that you are skipping ten to get the second nb which is 30 and keep on going on to get 50
2x² + 5x -6x - 15 = 0
2x² - x - 15 = 0
2x² -x = 15
x = 3
3 x 3 = 9 x 2 = 18 - 3 = 15
i really don't know how i got 3 in the first place but that is your answer
hope this helps
Answer:
ghg
Step-by-step explanation:
Plug in 0 for x
0 - 6y = 30
y = -5
Y intercept: (0,-5)
Plug in 0 for y
5x = 30
X = 6
X intercept: (6,0)
So, what you would have to do is figure out how old he is not which is 30 yrs old because it is half of 60.
So, after this you would have to find a number that would go into 60 four times which is 15.
So, your answer would be 15.
HOPES THIS HELPS!!!!
