A reasonable estimate for 8.24 divided by 4 would be 2. This would be a reasonable estimate because .24 rlly isn’t all that much so you are able to round down to 8. (Hope that’s right!)
2/3:2 = 1/3:1 The last one is in simplest form.
Answer: (-9, -3)
Step-by-step explanation:
A = (-3, -1)
A' = (-3, -1)*3 = (-9, -3)
Answer:
495
Step-by-step explanation:
In order to find the sum of the first 18 terms you have to find the 18th term and the first term using the equation given.
a1=3(1)-1 a1=2
a18=3(18)-1 a18= 53
Then plug in 53 for an, 18 for n, and 2 in for a1 in the sum equation: Sn=n/2(a1+an)
Sn=18/2(2+53) Solve for sn= 495
Add 11 to both sides:
-4=-2t
divide 2 by both sides
2=t
