153 000 = 100 000 + 50 000 + 3 000
Answer:
-2n²
Step-by-step explanation:
Using the image attached:
We see that the second differences (blue ones) are all equal so we conclude that this is a quadratic sequence.
The quadratic sequence has the form:
To find the value of a we just divide second difference ( -4 ) by 2:
Now we have:
Substitute 
and 
into the equation above:
Since 
= -2 and 
= -8 , after simplification we have:
The solution of this system is:
The general term is :
.5(20x-50y+36)-.25(-100x+40y-12)
10x-25y+18+25x-10y+3
35x-25y+18-10y+3
35x-35y+18+3
35x-35y+21
Answer:
2/3 ounces
Step-by-step explanation:
one pound is 16 ounces
1/3 of 16 ounces is 16/3
(16/3) ÷ 8 = (16/3) * (1/8) = 2/3
Answer:
Step-by-step explanation:
10x+ 150=220 is the equation for the second plan you subtract 150 from 220 to get 70 and divide that by 10 and you get 7 which is the number of weeks it'll take
220/25=x
So for this one it'll take 8.8 weeks to get enough money and you divide 220 by the amount which is 25 to get 8.8 the number of weeks I'll take
I dont understand what the second one is asking so sorry dude but I think that's right
