Answer:
the ten-thousands place
Step-by-step explanation:
Answer: Hence, Option 'A' is correct.
Step-by-step explanation:
since we have given that
Cost of per cans = $0.90
Let number of cans of Tuna be n
so, Total cost of n cans be
![0.90\times n\\\\=0.90n](https://tex.z-dn.net/?f=0.90%5Ctimes%20n%5C%5C%5C%5C%3D0.90n)
Amount of coupon Tuna get off on total purchase = $0.40
So, According to question,
![C(n)=0.09n-0.40](https://tex.z-dn.net/?f=C%28n%29%3D0.09n-0.40)
Hence, Option 'A' is correct.
Question: How many nickels and pennies when there are 65 coins that add up to a value of 1.73?
A. solution requiring no pencils, no calculators
If all coins are pennies, it would be worth 0.65, with (1.73-0.65)=1.08 left over.
We can change a nickel for a penny for (0.05-0.01)=0.04 (4 cents), so
number of nickels = 1.08/0.04=27
number of pennies = 65-27=38
Answer there are 38 pennies and 27 nickels
B. solution using a linear equation
Let n=number of nickels, then (65-n)=number of pennies.
Total value (cents) = 173 = 5n + (65-n) = 65+4n
Solve for n = (173-65)/4=27 ( number of nickels)
and (65-n)=38 (number of pennies.
Answer there are 38 pennies and 27 nickels
C. solution using a system of equations
Let
n=number of nickels
p=number pennies
Total number of coins
n+p=65 ..................(1)
Total value in cents
5n+p=173..............(2)
Solve for n and p
(2)-(1)
5n-n+p-p=173-65
4n=108
n=27 (27 nickels)
p+n=65
p=65-n=65-27=38 (38 pennies)
Answer there are 38 pennies and 27 nickels
2 times a number (m) plus 7
65 = 12.1+h the flower is 65 inches. it has grown 12.1 inches since the last time he measured it. the last time he measured it, it was height h.
65 = 12.1 + h
subtract 12.1 from both sides
65-12.1 = 12.1 + h- 12.1
52.9 = h
The last time he measured it it was 52.9 inches
