Answer:
There are 14 dimes and 17 nickels.
Step-by-step explanation:
Let x be number of nickels and let y be number of dimes.
Given that the total is $2.25 and there are 31 coins, we know that:
Solving for x yields:
We then proceed by plugging that back into the previous equation:
--> Distribute
--> add y's together
--> subtract 1.55
--> divide by 0.05
Therefore, x must equal 17, which means you have 14 dimes and 17 nickels.
Answer: the number of small boxes shipped is 14 and the number of large boxes shipped is 12.
Step-by-step explanation:
Let x represent the number of small boxes shipped and
Let y represent the number of large boxes shipped.
A total of 26 boxes of paper were shipped. This means that
x + y = 26
The volume of each small box is 7 cubic feet and the volume of each large box is 13 cubic feet. The combined volume of small and large boxes shipped is
7x + 13y = 254 - - - - - - - - - - - - - - - -1
Substituting x = 26 - y into equation 1, it becomes
7(26 - y) + 13y = 254
182 - 7y + 13y = 254
- 7y + 13y = 254 - 182
6y = 72
y = 72/6 = 12
x = 26 - y = 26 - 12
x = 14
