What are the first five partial sums of the arithmetic sequence an = 0.05(n – 1) – 0.6?
Gnoma [55]
The sum of the arithmetic sequence given by
<span>an = 0.05(n – 1) – 0.6
will be given by:
a1=0.05(1-1)-0.6=-0.6
a2=0.05(2-1)-0.6=-0.55
a3=0.05(3-1)-0.6=-0.5
a4=0.05(4-1)-0.6=-0.45
a5=0.05(5-1)-0.6=-0.4
thus the summation will be:
-0.6+(-0.55)+(-0.5)+(-0.45)+(-0.4)
=-2.5
hence
S5=-2.5</span>

What does this equal?<br><br> 6(x+1)+5=13-2+6x
natta225 [31]
<span>Simplifying 6(x + 1) + 5 = 13 + -2 + 6x Reorder the terms: 6(1 + x) + 5 = 13 + -2 + 6x (1 * 6 + x * 6) + 5 = 13 + -2 + 6x (6 + 6x) + 5 = 13 + -2 + 6x Reorder the terms: 6 + 5 + 6x = 13 + -2 + 6x Combine like terms: 6 + 5 = 11 11 + 6x = 13 + -2 + 6x Combine like terms: 13 + -2 = 11 11 + 6x = 11 + 6x Add '-11' to each side of the equation. 11 + -11 + 6x = 11 + -11 + 6x Combine like terms: 11 + -11 = 0 0 + 6x = 11 + -11 + 6x 6x = 11 + -11 + 6x Combine like terms: 11 + -11 = 0 6x = 0 + 6x 6x = 6x Add '-6x' to each side of the equation. 6x + -6x = 6x + -6x Combine like terms: 6x + -6x = 0 0 = 6x + -6x Combine like terms: 6x + -6x = 0 0 = 0 Solving 0 = 0 Couldn't find a variable to solve for. This equation is an identity, all real numbers are solutions.</span>
