A = 20, b = 70, c = 20, e = 110, d = 70
Answer:
{8, 9, 10}
Step-by-step explanation:
Let's substitute each of the values to see if it makes sense.
8 + 7 < 18; 15 < 18
9 + 7 < 18; 16 < 18
10 + 7 < 18; 17 < 18
11 + 7 < 18; 18 = 18
Therefore, the answer is {8, 9, 10}.
Hope this helps!
The equation would be 4y=5x 4(x+15)=5x x+15=y
let x be the amount that Shelia deposits each time
let y represent the amount that Sherri deposits each time
4(x+15)=5x
4x+60=5x
-4x -4x
60=x
Check:
x+15=y 60+15=y y=75
4(75)=5(60)
300=300
Shelia deposits $60 each time.
Answer:
A=10,000(1+.02/12)^4*t
Step-by-step explanation:
First off u need to know how many years to get the answer but for the rest:
P- is principle and is the amount you are starting with, in this case 10,000.
You can either use 1+ or 1- this depends on wheather the amount is increasing or decreasing
Increasing: 1+ ; Decreasing: 1
(The problem already has it for you)
R- is the rate, here you take the percentage and move the decimal twice to the left. In this problem 2% moved to the left is .02.
N- Depends on what the problems says
Quarterly- 4 (cuz it means 4)
Daily- 365 (Number of days in a year)
Weekly- 52 (Number of weeks in a year)
Monthly- 12 (Number of months in a year)
Yearly- 1 ( One year)
Finally you square the number of years by the N.
