Answer:
B. 13
Step-by-step explanation:
I calculated it logically
2(x+10)+3x=85
2x+20+3x=85 I used Distributive property
(2x+3x) +20=85 Combine like terms
5x+20-20=85-20 now i need to get rid of the 20 so i subtract it (the reason for this is because it is positive you have to so the oposite, in this case subtract) from that side, and what you do to one side you have to do to the other
5x=65 is what you have now
5x/5=65/5 Now i need to get rid of the 5 by divition, so i do it to both sides
x=13 is the answer
Branliest please!!!
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>
