It takes 3/9 to make 1/3.
You multiply the 1 (in 1/3) by 3, and you multiply the 3 (in 1/3) by 3. You get 3/9. You needed to multiply by 3 to make 1/3 have a common denominator is 9.
There are 10 people and you want each of them to have 3 cupcakes. So multiply 10x3, which is 30. Then divide 30 by 8. You can't do that without a remainder though. So you round up to the nearest multiple of 8, which is 32. Then divide 32 by 8, which is 4. So tell dad to bake 4 batches, and the rest is for your dessert tomorrow.

Answer: The required system of equations representing the given situation is

Step-by-step explanation: Given that Sam needs to make a long-distance call from a pay phone.
We are to write a system to represent the situation.
Let x represent the number of minutes Sam talked on the phone and y represents the total amount that he paid for the call.
According to the given information,
with prepaid phone card, Sam will be charged $1.00 to connect and $0.50 per minute.
So, the equation representing this situation is

Also, if Sam places a collect call with the operator he will be charged $3.00 to connect and $0.25 per minute.
So, the equation representing this situation is

Thus, the required system of equations representing the given situation is

Answer:
rule: f(n) = n³
missing numbers: 125, 216, 343, 512, 729
Step-by-step explanation:
Your familiarity with the cubes of small integers helps you recognize each of these numbers is a cube. Their sequence is the sequence of cubes of increasing natural numbers.
1 = 1·1·1 = 1³
8 = 2·2·2 = 2³
27 = 3·3·3 = 3³
64 = 4·4·4 = 4³
__
The rule is ...
f(n) = n³
The cubes of 5 through 9 will complete the set of numbers ...
1, 8, 27, 64, 125, 216, 343, 512, 729
