Y=8
A horizonal line means y equals something. When you have a given point on the horizontal line you know the answer, which is the value of y in the given point.
Answer:
4/3
Step-by-step explanation:
You add the top numbers and not the bottom then simplify.
Sum of n terms of a geometric series is
Sn = a1 (r^n-1)/(r-1)
a1 = 1st term = 4
r = common ratio = 12/4 = 3
so, the sum is
Sn = 4 (3^n-1)/(3-1) = 2(3^n-1)
2.5 divided by 2 equals 1.25 so each side equals 1.25
Answer:
39
Step-by-step explanation:
Let the smallest number be n,
then the three numbers are n, n+1 and n+2
Therefore, n+(n+1)+(n+2)=120
Collecting like terms,
n+n+n=120-1-2
3n=117
n=117/3
n=39
Therefore the numbers are 39,40 and 41.
And the smallest number is 39.
