Answer:
126.
Step-by-step explanation:
One way to do this is to see if 126 is divisible by 6,9 and 18. If so then the LCD is 126.
Use your calculator to check.
It is 126.
This is geometric with a common ratio of 3 (3/1 = 3 and 9/3 = 3 etc)
the formula for the nth term is
an = 3^(n-1)
Answer:
y-3x-9=0
Step-by-step explanation:
(x1,y1)=(-3,0)and (x2,y2)=(-2,3)
Now,
y-y1=(y2-y1)/(x2-x1) (x-x1)
y-0=3-0/-2-(-3) (x-(-3))
y-0=3/1 (x+3)
y=3x+9
y-3x-9=0
Answer:
12.25 miles
Step-by-step explanation:
We can write a proportion to solve. Miles over time in minutes
1 hour = 60 minutes
1 hours 10 minutes = 60+10 = 70 minutes
3.5 miles x miles
--------------- = --------------
20 minutes 70 minutes
Using cross products
3.5 *70 = 20x
245 = 20x
Divide each side by 20
245/20 = 20x/20
12.25 =x
Jimmy can go 12.25 miles
Okay, are you saying:
-a = 2, b = 2, c = 2, solve (a + b + c)
or
-2a * 2b * 2c(a + b + c)
