Answer
7 = -x
Step-by-step explanation:
18- 8x = 8 + 3(1 - 3x)
18- 8x = 8 +3-9x
18- 8x = 11 - 9x
7- 8x = -9x
7 = -x
First you write down all even integers that divide 20.
Those are: 2,4,10,20
Since the request is that integer is less than n, 20 cannot be the answer.
This means that greatest even integer is 10
Answer is 10.
Step-by-step explanation:
the formula for the sum of the first n terms of a geometric sequence is
Sn = s1(1 - r^n)/(1 - r)
with r being the common ratio and s1 is the first term.
so,
S15 = 7×(1 - (-3)¹⁵)/(1 - -3) = 7×(1 - -14,348,907)/4 =
= 7×14,348,908/4 = 7×3,587,227 = 25,110,589
In the proportion 4:16 = x:32. The answer is 8
4/13.6 = 0
(X/3)/4 = 24
x^2-(7*x)+12 > 0
(1/2)*x^2 = -7
(1/3)*p^2 = 1/4
