Let x be the number. x= 2x-17
-x=-17
x=17
this is kinda easy and im gonna assume that the 4 is a exponent cuz f(2)=2(3)^4 then f=81
You can make a table like this:
If 1 bag=5 pounds
Then 6 bags must equal six times the weight of the first bag
5 times 6=30
Your answer is reasonable because 5+5+5+5+5+5=30
a.k.a
=5 =30
Let the number be x.
Half of that number = x / 2
One third of the number = x / 3
= x / 2 + x / 3 = 22. LCM = 6.
= (3x + 2 x) / 6 = 22.
5x / 6 = 22. Cross multiply
5x = 6 * 22.
5x = 132 Divide both sides by 5.
x = 132 / 5
x = 26.4
The number is 26.4. Cheers.
Answer:
Step-by-step explanation:
This is a geometric sequence; we know that because of the words "common ratio." The general formula for a geometric sequence is
a(n) = a(1)*r^(n - 1), where r is the common ratio.
Here, a(1) = 1, r = 1/3, and so
a(1) = 1 (given)
a(2) = 1/3 (this is a(1) multiplied by 1/3)
a(3) = 1/9 (this is a(2) multiplied by 1/3)
a(4) = 1/27
a(5) = 1/81
