Answer:
C. 4 weeks
Step-by-step explanation:
Trish and Aria are walking to raise money for the school library. Trish has walked 38 miles and walks 10 miles each week. Aria has walked 30 miles and walks 12 miles each week
After how many weeks will Trish and Aria have walked the same number of miles? A. 2 weeks B. 3 weeks C. 4 weeks D. 5 weeks
Trish = 38 + 10x
Aria = 30 + 12x
Where,
x = number of weeks
After how many weeks will Trish and Aria have walked the same number of miles?
Equate both equations
38 + 10x = 30 + 12x
38 - 30 = 12x - 10x
8 = 2x
x = 8/2
x = 4 weeks
Answer:
All the values smaller than or equal 3
Step-by-step explanation:
Any function has domain and rang, the domain is the values of x and the range is the values of y so when ask about the range that means all the values of y which including the graph the graph is downward starting from 3 on the y-axis and go to negative infinity so the answer is all the values smaller than or equal 3
Since there are 120 payments in total
Then the total
interest paid is $ 9,118.32
The monthly interest = $ 9,118.32 / 120
The monthly interest = $ 75.99 per month
% total interest = ( $ 9,118.32/ 29,118.32) x 100
% total interest = 31.31 %
You would start by finding out how much 10 and 20 cost per copy
10: 40-25 = 15/10 = $1.50 dollars per copy
20 (This is for checking your math, not required): 55-25 = 30/20 = $1.50 dollars per copy
So, to find 15 copies you would use this formula: 25 + 1.5x
25 + 1.5(15)
25 + 22.5
$47.50 for 15 copies
Now for the second question:
160 - 25 = 135/1.5 = 90 copies
90 copies for $160
